League of Legends Acronyms and Terms Glossary

League of Legends Acronyms and Terms Glossary by Father Tunde

I know there have been many of these all over the place, but most of them are not complete in some way or the other. So here’s a better one.

Ace – When all champions on the enemy team are dead.
AD – Attack Damage
AD Carry – See carry
AFK – Stands for away from keyboard. But is often used to refer to someone who is not moving, whether he is away from keyboard or not.
Aggro – To have tower aggro means the tower is targeting (and so attacking) you. You can lose tower aggro by stepping out of range of the tower. You can gain tower aggro by being the first to step within tower range. Or if you enter within range of the tower, say after your minions, then you can still get tower aggro by attacking an enemy champion while under the tower.
AoE – Area of Effect. AoE spells are spells that do damage in an area as opposed to just on one target.
AP – Ability Power
AP Mid – The mage that takes the mid lane. See laning arrangement at the bottom of this page for more info.
ArP – Armor Penentration. The more ArP you have, the more armor of you ignore of the enemy you are attacking, and so the more damage you do.
AS – Attack Speed. The number of times your champion can autoattack per second. The maximum is 2.5 attacks per second.
Assassin – The role of the assassin is to sneak or jump past the tanks (ignoring them completely) and go straight for the enemy squishies at the back (e.g. the carry). They do a lot of burst damage and usually do not stay in the fight for long. (definition provided by fightknights)
Atmogs – Warmogs + Atmas Impaler

B – Back; when someone is told to b that person is being told to retreat. If someone’s say that they will b, they intend to retreat or recall.
Bait – Someone who is used to lure enemy champions. Usually your team will be ready to jump on the enemy as soon as they attack the bait.
Ban – In ranked games and draft mode games each team can ‘ban’ three champions at the start of champion selection. If a champion is banned he cannot be played by either team for that game
– Ban could also refer to banning an account from playing or from posting on the forums. Forum bans are handed out by Riot when a player breaks the forum rules too often.
Banning an account from playing is done using The tribunal.
At the end of each game should you think fellow players have shown unacceptable behaviour you can report them (by clicking on the exclamation mark next to their name on the end game screen) for one of several offenses. If a player gets enough reports their case will be sent to the tribunal. See tribunal for more information.
Riot can also ban players instantly, without using the tribunal, if they feel it is necessary.
Baron/Baron Nashor – The very large wyrm-like creature in the top half of the river in Summoner’s Rift.
BD – Backdoor; to attack a tower without any minions.
BF – B.F. Sword. Item in the shop that gives loads of AD. (kudos to zigomorfico)
BG – Bad game. This can be said by the winning team should the losing team have a disconnection or an afk as a means of good sportsmanship, in recognizing that they won because it was an uneven match and not because they are better. Similarly, it can be said by losing team to indicate that they didn’t think it was a good game because they had a dc, afk, troller, or whatever.
This can also be used by ragers to indicate that it wasn’t a good game because they played badly or because their team was bad.
Blue – Could refer to the blue golem or to the blue buff (which you get for killing the golem).
Blue pilling – An old school phrase meaning recalling.
Bot – Refers to the bottom lane in Summoner’s Rift, the bottom capture points in Dominion or the bottom lane in Twisted Treeline. See laning arrangement in the next post for more info on who goes here in Summoner’s Rift.
Brb – Be right back. This could refer to real life (as in someone is going to the toilet) or in game (as in someone is going to buy items).
BT – Bloodthirster
Buff – Something that makes a champions stronger in some way e.g. red buff, an aura of magic resistance, etc.
Build – The set of items you buy for your champion.
Burst – Dealing a large amount of damage in a short time, also called nuke.
Bush/brush – The tall grass on every map in which you can hide.

Care – Asking someone to be careful.
Carry – The meaning of carry varies from player to player, and so it’s hard to pinpoint one exact definition that will encompass all meanings. A carry is a champion who is very weak early game and so needs to be ‘carried’ by his team in order to survive. But is extremely strong late game and then does most of the continuous damage of the team and so can ‘carry’ the team. These champions are usually champions that rely on autoattacks for their main damage output (in which case they are called AD carries – because the items they buy focus on their Attack Damage) , and autoattacks only really start to do a lot of damage when you have a lot of items to support them, hence why you’ll only be strong late game, when you have all your items. Carries often go in the bottom lane together with a support champion who supports/helps/carries them during their difficult early laning phase. Even during mid and late game, though they have a high damage output, they will still be very squishy and so will need a tank or other champions to protect or ‘carry’ them.
Some champions are sometimes referred to as AP carries, these would be champions that are able to put out a continuous large amount of magic damage in late game (but usually throughout the game).
Players often say ‘I carried this game’ or ‘I carried this team’ and this is not a reference to one of the specific definitions above but just a general way of boasting and saying they were the best on their team and they were the deciding factor in bringing their team to victory.
CC – Crowd Control; a set of debuffs, such as silence, blind, slow, stun, snare, etc. that limit movement or prevent a certain ability or autoattack from being used.
CD – Cooldown. Refers to the number of seconds you have to wait before you can use an ability after you have just used it. When an ability is said to be on cooldown, this means you can’t cast it yet and have to wait until it is ‘off cooldown’ before you can cast it again.
CDR – Cooldown reduction.
Counter jungle – To kill monsters in the enemy jungle instead of your own. Sometimes not all the monsters from a monster camp are killed, but instead one small unimportant monster is left so that the camp does not respawn. Jungle monsters respawn after a certain time but this timer only starts when all the monsters from a certain camp are killed. If one small monster is left, then the enemy jungler has to first kill this monster and then wait the duration of the timer before he can kill the full camp, making him fall behind even more.
CP – Refers to a capture point in dominion.
Crit – Critical strike. When a champion attacks with his autoattack, they have a chance of critical striking the enemy. If this happens the autoattack will do extra damage (200% of the normal damage – so an extra 100% – or twice the normal damage). By default, this chance of critically striking is 0%. You can increase this up to a maximum of 100% with items, runes and certain abilities. You can buy items so that your crit chacne goes above 100%, but you wont gain anything from this. You can also increase the damaged gained from critically striking with runes, masteries and items (up to a maximum of 305% damage). You cannot critically strike on towers or inhibitors.
CS – Stands for creep score, this refers to the total number of minions and monsters killed.
CV – Clairvoyance

DC – Disconnected/disconnection/disconnect
Debuff – Something that makes a champion weaker in some way. E.g. Slow.
Def – Defend
Deny – To deny the enemy something basically means to prevent them from having something. When denying xp and cs in lane it is called zoning.
Dive – To dive or tower dive someone is to fight them under their turret. This means that you will get attacked by the tower while you fight him and so receive a lot of damage.
DPS – Damage per Second
Dr – see drag.
Drag – Dragon; this refers to the dragon that resides in the bottom half of the river on Summoner’s Rift or the towards the top of the map in the Twisted Treeline. If it has a number next to it like ‘drag 32:25’ this will usually be the time that it respawns.)
Drake – Dragon. See drag.
Duo lane – A lane with two players in it. See laning arrangement in the next page for more info.
Durable – Having high health, armor and magic resistance and so being hard to kill.

Elo – Your rating in a ranked game.
Exchange – An exchange is when you exchange damage with your opponent. Usually, in lane, when you go to harassyour opponent, they will face you and do some damage back. If you deal much more damage than you take then that was a good exchange. If you take much more damage (be it from minions or the enemy champion) than you deal then it is a bad exchange. If you deal damage but receive none, then it is not an exchange, but just free harass.

Facecheck – To check a brush for enemies by going in headfirst without using wards, clairvoyance, or any other means. Note: this is not recommended.
Faceroll – Originally, to faceroll was to roll your face on the keyboard and so press all the keys. Some champions are said to be faceroll champions because in order to play them you just have press all your buttons.
Nowadays, however, facerolling is also used to describe getting so fed and killing so many champions that ‘faces[heads] are rolling’.
Farm – To kill minions and get gold. Someone who is well farmed has a lot of cs.
FB – First blood; the first kill in the game. This kill gives you 400 gold instead of the usual 300 gold.
Feed – To feed someone is to give them a lot of kills. If someone is fed (or feeded if their English is not that good ) it means he/she has a lot of kills. If someone is a feeder, it means he/she is dying a lot.
FM – Frozen Mallet
Focus – To attack the same person in a teamfight/ E.g. ‘Focus Katarina first’ means that everyone should attack Katarina first, until she is dead or out of reach.
FotM – Flavour of the Month i.e. the champions,items,strategies, etc. that are popular at the time.
Fratmas – Frozen Mallet + Atma’s Impaler
Freeze/Frozen – When a lane is frozen this means the outer tower has been destroyed and the minions now meet far beyond this tower. If the team that lost the tower now only last hits then the lane will stay frozen. Assuming the towers in other lanes are still there this means that it is now very dangerous for the team that killed the tower to stay in lane and attack minions as they could then easily be ganked. This means that the player that just destroyed the tower cant farm safely and so is forced to roam around the map. For this reason it is sometimes not advisable to take down a tower very early in the game. The team that just lost the tower can of course unfreeze the lane by pushing the lane back (not only last hitting).
FTW – For the Win. Can be used to describe that something was good/ lead to the victory of this game (e,g, Heal-bait ftw!) or ironically to say that something wasn’t good at all and did the total opposite of winning a game (e.g. yes, go in 1v5 ftw!) (definition by Metzelmax)
FU = Stands for f*** you. More often than not this is meant in a friendly way to express frustration. Fuuuuuuu would be used at elevated levels of frustration and would be equivalent to f*** youuuuuuuuuuuu.

GA – Guardian Angel
Gang – Misspelling of Gank
Gank – To gank someone is usually to sneak up to someone with the intention of killing him. The player being ganked usually does not expect this otherwise it would just be a ‘fight’.
GG – Good game. A polite phrase showing good sportsmanship said at the end of the game. However, it is also sometimes used to signal that the game is already over. E.g ‘Omg, they have a fed Akali, it’s gg!’ This means ‘because they have a fed Akali the game is probably already over’.
GG easy – Suggests it was an easy victory. Usually meant as an insult.
GJ – Good job. Often said to a teammate when he/she did something very good, or to the team as a whole after a successful fight. It is also often used sarcastically after someone does a terrible job.
GL – Good luck.
Golems – Monsters in the jungle. Can refer to the blue or red golems, but usually refers to the other (pair of) golems – the ones near the center of the top most and bottom most lane. *For those that do not know what golems normally look like: in league of legends they can be distuinguised from other jungle monsters in that they are the only ones that stand upright on two feet*. (kudos to zigomorfico)
GP – Gangplank
GP5 – Gold per five seconds. Gold gain is usually measured in per 5 seconds, like mana regen and hp regen.

Harass – To deal significant damage to someone frequently. This is different from a fight and is usually used in the laning phase where the enemy slowly gets lower and lower in health so that eventually he will need to recall to base or will be low enough for you to jump on him and kill him.
HF – Have fun
Hold– Hold can have one of three similar meanings.
– Asking someone to hold your lane is asking them (e.g. the jungler) to take over your lane while you are recalling so that the enemy doesnt push the lane to your tower.
– Telling someone to hold a lane could be telling them to freeze the lane. For more information see freeze (kudos to zigomorfico)
– Asking your team to hold a certain to tower could be asking them to defend the tower. For example to keep the enemy busy while you push a different tower.
HP5 – Health regeneration per 5 seconds
Huehuehuehue = An onomatopoeia for an exaggerated laugh. Often written after ‘Morde es #1’, after being popularized in this thread: http://na.leagueoflegends.com/board/…d.php?t=316408
Hug – See tower hug.

Idd – Indeed
IE = Infinity Edge
Inc – Incoming
Imba – Imbalanced
Initiate – To be the first to engage in a fight.
Innate – A ‘5th ability’ that every champion has and starts off with at lvl 1. This ability can be seen to the left of your q ability and is usually minor compared to your other abilities. Often called ‘unique passive’ or simply ‘passive’. Technically, your innate is a passive ability, but not every passive ability is innate.
Invade – To go into the enemy’s territory, particularly their jungle. This is usually done to steal the enemy’s Red Buff or Blue Buff. Invading usually refers to the very start of the game, before minions spawn. If something similar is done later in the game, it is simply called counter jungling. (adapted from zigomorfico)
IP – Influence points; points that you get by playing games with which you can buy champions, runes and rune pages.

Juke – To trick someone into going the wrong way when he/she is chasing you. This is often done by being invisible for a few seconds using the brush, the fog of war, akali’s twilight shroud, etc.
Jungle – Refers to almost everything that is not lane or base. It is where the jungle monsters reside. There is no jungle in Dominion.
Jungler – The player who mostly stays in the jungle and gains gold from killing the monsters there (does not apply in Dominion). See laning arrangement in the next post for more info.

KS – Killsteal. To steal a kill from someone by getting the last hit on the champion. See the section on stealing in the next post for more info.
Kite – To kite is when you stay at a distance (with your ranged champ) from your opponent and attack them from that distance, so they cant attack you. The term comes from a kite, an airborne device that is always at equal distance from you because you hold it with a string. Ashe is very good at this as her attacks slow the opponent and so keep the opponent from getting to her. [kudos to Alarus for adding and to fightknights for defining]

L2P – Learn to play
Leash – See pull.
Lane – One of the (three in Summoner’s Rift and two in Twisted Treeline) ‘roads’ on the map.
Lifesteal – Allows you to regain part of the damage you dealt as health. For example: If you dealt 100 damage and had 10% lifesteal you would get 10 health back. Lifesteal only applies to autoattacks and a few abilities. Whereas spell vamp applies to most magic spells and some other things. Lifesteal percentage is divided by 3 for multi-target spells.
Line – Misspelling of lane

Meta– Short for metagame. The game’s current play style, consisting of aspects such as lane setup, jungling, and team composition. ( definition from the wiki). For example the current metagame is: 1-1-2 + 1
top lane: 1 tank, bruiser or second ap
mid lane: 1 AP carry
bot lane: its a duo lane, with 1 support and 1 AD carry
jungle: usually a bruiser, but can be a tank too
(kudos to zigomorfico)
Metasheep – Someone who (blindly) follows the current meta. Usually used a pejorative term.
MF – Miss Fortune
Mia = Missing in action – see SS
Mid – Refers to the middle lane in Summoner’s Rift, the middle capture points in Dominion or sometimes the top lanein Twisted Treeline. See laning arrangement in the next post for more information on who goes here on Summoner’s Rift.
Miss – See SS
Could also refer to Miss Fortune (though usually mf is used) kudos to somersetsaxon
MP5 – Mana regeneration per five seconds
MrP – Magic resistance penetration or simply magic penetration. The higher your MrP, the more magic damage you do to enemies with magic resistance.
MS – Movement Speed

N1 – Nice one.
Nerf – To weaken a certain a characteristic of the game, usually a champion, in order to balance the game. E.g. making Annie’s bear deal less damage. Nerfs are usually done every two weeks with the regular patch.
Noob/Newb/Newbie/Nub/Nab – Originally termed to be a beginner. But is now used more often to refer to someone who is a bad player.
Np – No problem
Nuke – Dealing a large amount of damage in a short time, also called burst. Sometimes people also use nuke to refer to dealing a large amount of area damage.
Nuke comes from nuclear bomb, which deals a large amount of damage over a large area in a short time.
Nuker – Someone who is capable of nuking.

OMW – On my way.
OOM – Out of mana.
OP – Overpowered or original post.
Overextending – A champion moving too far in lane/enemy territory, which can open them up to ganks. Sometimes it’s hard to tell whether someone is overextending or split pushing. (definition by zigomorfico)

Passive – An ability that has a more permanent effect. This can be a q, w, e, r or innate ability. But most often, when people say passive, they simply refer to your innate. See innate for more information.
PD – Phantom dancer
Pink – or pink ward, refers to a vision ward (the expensive one that can detect stealth). This could also refer to an oracle (though im not sure).
Poke – A form of harass which uses long ranged attacks to cause small to moderate damage in order to weaken an enemy, while keeping a safe position. Used often before fights or when fighting for objectives like dragon or nashor. (definition by zigomorfico)
Proc = Activate/trigger. This can be used in a variety of scenarios. Some examples:
– Heimerdingers concussion grenade procs spellvamp. This means that the damage that Heimer’s grenades do replenishes some of Heimer’s health.
– Passive toggle abilities such as Warwick’s blood scent or Ashe’s frost shot do not proc Sheen’s effect but active toggle abilities such as Nidalee’s aspect of the cougar and Swain’s ravenous flock do.
– Ezreal’s Mystic shot will proc any on-hit effect such as the slow form Frozen Mallet or the damage from Sheen.
– Ezreal’s Mystic shot will proc lifesteal, but not spellvamp.
– Poppy’s devastating blow will proc spellvamp, but not lifesteal.
A confusing but clarifying example:
‘Ezreal’s mystic shot procs Sheen’ can to the fact that Sheen’s passive is activated by the use of mystic shot but can also refer to the fact that the passive of sheen is used up (and the extra damage is done) with the use of mystic shot. Thus when Ezreal who has Sheen uses his mystic shot, the sheen buff is added to Ezreal and then immediatly used up again as the mystic shot lands.
Basically, the use of the word proc cannot be defined exactly, but the meaning can often easily be deduced from the context.
For more information on the origin of the word (but which doesnt really help understand it :S):http://www.nerfbat.com/2006/04/15/what-is-a-proc/
Pull – A pull is the first hit on a jungle monster, done by someone other than the person going to kill the monster. For example: if Warwick wants to kill the blue golem then Brand could do the first hit on that golem and then go away. This ensures that the blue golem will end up chasing Brand for a while before attacking Warwick. During this time Warwick can keep hitting the blue golem without taking any damage. It will usually be a few seconds before the blue golem realizes Brand is gone and will start attacking Warwick. These few seconds can often make the difference between the jungler being able to kill the blue or not being able to kill the blue golem (though in this case with Warwick as he can always take on blue easily).
Push – To advance in lane towards the enemy nexus with the intention of destroying towers, inhibitors or the nexus.
Push to win – Signals one final push in which you expect to destroy the nexus and end the game.

QQ – When used as capitals, these look like a set of crying eyes and so refer to someone who is crying/raging.
QSS – Quicksilver Sash

Ragequitter – Someone who leaves the game out of anger or frustration.
Rat – Could refer to Twitch.
Re – see SS.
Red – Could refer to the red golem or to the Red buff.
River – The large river that runs from the left top to the right bottom of Summoner’s Rift.
Roam – A player/champion is roaming when they are not staying in one place (or lane) but rather moving across the map constantly to gank other lanes, invade jungle, etc. This is sometimes referred to a seperate role and in this case usually replaces the support. Alistar is a good example of a champion who can play support but can then suddenly go roaming when necessary because of his strong supporting and strong ganking abilities.
RP – Riot points; points that you get buy paying real money or winning competitions with which you can buy champions, skins, name changes, and other things.

Shop – The in-game shop in your base where you can buy items for your champion with gold. Not to be confused withstore.
Silence – Someone who is silenced cannot cast any abilities. There are some exceptions however, such as Cleanse, and Tryndamere’s ultimate.
Skillshot – An ability which does not lock on to your target, and so you need to aim properly in order to hit an enemy.
Snowballing – Snowballing means getting stronger exponentially. Meaning that the more kills you get, the stronger you get and so the more kills you are able to get, etc. Snowballing is usually said when referring to items which get stronger the more kills you get such as Sword of the Occult,
Mejai’s Soulstealer, etc.
Solo top – Refers to the top lane (usually in Summoner’s Rift) when held by one champion. See laning arrangement in the next post for more info.
Spell vamp – Allows you to regain some of the damage you dealt with spells as health. Similar to lifesteal. Whereas lifesteal applies to autoattacks, spell vamp applies to spells and other magic damage. Spell vamp percentage is divided by 3 for multi-target spells.
Split push – Split pushing is when two parties are pushing in different lanes. I.e. If all five team members are pushing mid lane, then they are all pushing. But if a group of four is pushing bottom lane, and the other player is pushing top lane then both parties are split pushing. Sometimes the word split pushing is also used when one party is pushing one lane and the rest of the team is not necessarily pushing a lane, but just distracting the enemies by fighting over baron or something.
Squishy – A champion is squishy if he/she is very easy to kill because of low max hp/armor or magic resisitance. The opposite of durable.
SR – Summoner’s Rift; the 5v5 map of League of legends.
SS – Stands for miss or missing. This is said when an opponent in a certain lane is missing and so could have left the lane to for example gank other players. Extra caution is advised when someone says SS. SS can be followed or preceded by more information. (E.g. top ss means whoever was in top lane is missing, ss annie means annie is missing from her lane, 2 ss bot means two champions are missing from the bot lane, etc.). In North America, MIA (missing in action) is used instead of SS and in Asia MS (missing) is used. When this champion returns to back lane, you say ‘re’ to let your teammates know.
Stack – This word can be used in many different ways but always involves multiplying the effect of something. A stack is originally a more or less orderly pile or heap: a precariously balanced stack of books. There are items that “stack” or “pile up” a certain value for each time you do a certain action like auto-attacking (e.g Guinsoo’s Rageblade), using a skill or killing a champion. There are items that stack values, but you can also stack items yourself (buying more than one). There are also skills that stack values (e.g. Soraka’s Starcall). [definition provided by fightknights]
Some more examples:
Riven is stacking Bloodthirsters = Riven is buying many Bloodthirsters (an item).
Katarina’s Mejai’s Soulstealer is at 15 stacks = i.e. her Soulstealer now gives 140 ability power.
The debuff from Soraka’s Starcall stacks up to a maximum of 8 = Each time Soraka hits someone with Starcall their magic resistance is reduced by 10 (with a level 3 Starcall). This keeps increasing everytime she hits them until their magic resistance is lowered by a total of 80. If it didnt stack then the maximum would be 10.
If an item is said not to not stack with another item, like Lichbane and Trinityforce, then the unique values will not add up and only the effect of one of the items will proc – in this case whichever effect does the highest damage)
I’m sure there are more examples I could find, but I hope that from this explanation and the context you see the word in its meaning will be clear enough. If not, let me know in the comments below!
Store – The ‘out-of-game’ League of Legends store in which you can buy champions, runes, and other things with RP or IP. Not to be confused with shop.
Steal – Specific definitions of this vary but always at least refers to getting the last hit on a unit when an ally was already attacking it. can refer to stealing a champion kill, a minion kill, or a jungle monster.This is usually meant in a negative fashion, as in: you ‘stole’ from your ally. But stealing is often used as a strategy and so can be used in a positive way. See the next post for more details on when stealing is good.
Stun – A debuff that completely shuts down someone. They are unable to move, attack, or do abilities for the duration of the stun. During a stun, there are only a very few things you can do, such as cast Cleanse, or activate Tryndamere’s ultimate.
Supp – Support. This is a champion or player who doesn’t take any minion last hits and so usually ends up with very little gold. This is usually a champion who can do quite well without much gold and their main purpose is to help out the ad carry in their difficult early laning phase and later help the team as a whole by placing wards, healing champions, providing beneficial auras or disabling the enemy champions. See laning arrangement in the next post for more info.
Suppress – When you are suppressed you cannot move, use abilites or autoattack. Warwick, Skarner and Malzahar have an ability than can suppress. Cleanse does not stop suppress. But quicksilver sash (item), gangplank’s remove scruvy, olafs ulti can. Tryndamere can cast his ultiamte while suppressed. If the champion that is suppressing (ww, mala or skarner) is stunned while he is suppressing, then the suppress ends.
Sustain – Long-term regeneration. E.g. a champion with a lot of sustain can stay in lane for a long time because they can keep regenerating their mana or hp so they never have to go back to base to heal. (kudos to zigomorfico)

Tank – Tanks are champions that are usually very durable and are supposed to initiate fights and take up most of the damage. Tanks often also have abilities that are useful to disable the enemy team such as stuns and silences or buffsthat help your team.
TF – Twisted Fate or teamfight.
TLDR – Too long didnt read.
Top – Refers to the top lane in Summoner’s Rift and Twisted Treeline or the top capture point in Dominion. Seelaning arrangement at the bottom of this page for more info on who goes here in Summoner’s Rift.
Tower dive – See dive. (kudos to zigomorfico)
Tower hug – To stay near your tower to deter enemy champions from attacking you. ((definition by zigomorfico)
TP -Teleport
Trade – see exchange
Tribunal – The Tribunal is a sophisticated reporting system that is used to separate the players who committed an offense from the players that didn’t.
Their case will be presented to fellow summoners who can decide to pardon (forgive) them or to punish them. If a player gets enough punishes he/shes will be banned. First you get a warning. Then you get a ban of a few days. The next ban is a few weeks, etc. And if you keep offending you will eventually get banned permanently.
Tribush/tribrush – The bush/brush in the shape of a star with three points near the top end and bottom end of the river. (kudos to zigomorfico)
Troll – A troll on the internet is generally someone who doesn’t take something seriously and deliberately tries to ruin something for those who are taking it seriously (though this could occasionally be in a more humorous and rather non malicious manner). In league of legends, a troll pick would be someone who purposely chooses a champion that is clearly a bad pick for the team. For example picking a support champion when the team already has a support and really needs something else, like an ad carry. Troll summoner spells would be spells that are clearly not useful and so are only taken for jokes, or to lose the game, or to make someone quit champion select, etc (these are usually surge, promote and revive). If someone is trolling, it means they are clearly not taking the game seriously, either by playing bad, feeding the enemy team, or trying out things that everyone knows wont work. This is a bannable offense (especially in ranked – not so much when you are just playing with friends).
-Could also refer to the Champion Trundle.
TS – Teamspeak. A program to communicate verbally like skype or ventrilo.
TT – Twisted Treeline; the 3v3 map of League of Legends

U2 – You too. Often said in response to ‘good luck and have fun’.
Ult – Ultimate. Refers to a champions 4th ability, which he/she can usually only pick at lvl 6.
Unique passive – An other word for innate. See innate for more information.

Vent – Ventrilo
Wave – Minion wave. A group of six or seven minions that spawn in every lane about every half a minute.
Wolves – Monsters in the jungle.
Wota – Will of the ancients – item in the shop.
WP – Well played.
Wraiths – Monsters in the jungle. The ones close to the middle lane.
WW – Warwick

Zone – To zone someone is to force them to go so far back in lane that they are too far away to be able to last hit the minions and too far away to get experience when the minions die. This is usually done by bringing so low on health that if they were to come closer you would just kill them. And so it is better for them to stay back and lose xp and money than to come closer and die. If you find yourself zoned on low health it is often advisable to go back to base to health to return to lane with full health.

Additional Info:

Laning arrangement

Some of the above words refer to how the players are divided across the lanes. Since these are all related, I thought it best to explain it all here in one place:
On Summoner’s Rift, there are five players. But there are only three lanes and one jungle. Usually one champion will go in the jungle and gain gold from killing those monsters. This leaves four champions for three lanes. This means one lane will have to contain two champions. Such a lane is called a double lane. Lanes with only one champion are called asolo lane. Usually the bottom lane is set as the double lane. This is because this way you have as many people as possible close to the dragon, so its easier to send loads of people there to fight and kill it. If it were just for dragon control, mid could also be a duo lane, but mid is usually reserved for a champion that is better ganking/helping other lanes, whereas the champions in the bottom lane are usually not very good at this. Mid lane is also usually reserved for mages, as they are very dependent on the blue buff and mid lane is closest to both blue buffs.

Hence mid and top are usually solo lanes. Mid is also sometimes referred to as AP mid, because mid is usually a mage, and mages always build AP. The champion who kills monsters in the jungle is referred to as the jungler. The bot lane is referred to as the duo lane. Since bot lane consists of two champions, the question now becomes: who will get the money from killing the minions? Should they all go to one champion or should they be divided equally between both champions? The answer is that usually they will put two very different champions in bot lane. One that scales super well with items/gold. And one that can do pretty well without any gold. The champion that scales very well with items (usually the ad carry) is then allowed to kill all the minions and hence get all the gold. Whereas the other champion, called the support champion, doesnt take any. The support is called so because he aids the team by supporting the other champions on the team rather than helping himself. The ad in the term ad carry comes from the fact that they always build ad (attack damage, critical chance, attack speed, etc.) as this is the build that has the highest damage output. For an explanation of why they are called carry, please see the the term carry in the glossary above

There we go, so thats how most games are usually arranged. The above strategy is referred to as the current meta-game, or the standard meta, or the normal meta.
Of course, as this is just a strategy, and not a rule, games are not always played this way.

Often at lower level games, with beginners, no one will feel really comfortable playing a jungler and so there could be no jungler at all, meaning you have two duo lanes.
Sometimes, a team could decide to send two people in the jungle, meaning that there will be three solo lanes. This allows for very powerful ganks as you are now jungling with two champions instead of one.
Occasionally, for whatever reason, a team could decide to send their traditional double lane to the top, or even to mid, and have a solo bot lane.
Sometimes, you have a player called a ‘roamer’ and he doesnt really stick to one lane, but instead just moves from lane to lane, trying to gank everyone.
Obviously, I’m sure you can come up with many other arrangements, but these are the most common ones.

Stealing, the strategy behind it

Killstealing
1. There are certain champions or roles that scale better with items than others. Typically the support champion will not scale as well with items as other champions. So it is best if the support leaves the kill to someone else. Typically, the ad carry scales the best with items, and so they should always get the kill if you have the choice.

2. When a champion is killed, there are two gold pools. One for assists and one for the kill. The kill money (usually 300) is always granted to one person, only the killer. The assist money is divided between all the people that assisted (i.e. also did damage within the last 10 seconds) in the kill. The assist pool does change depending on the number of people that assisted. However, if no one assisted then no assist money will be awarded. Therefore, say, you are about to kill someone alone, and your ally has the choice of killing the opponent or not doing any damage, then it would be better for him to kill him because you are also awarded assist money. If your ally doesn’t killsteal, you would get the kill gold and thats it. Now he is awarded the kill gold and you the assist gold and so that means more TOTAL gold for your team. If an ally champion has already assisted then there is usually no point in having another ally steal the kill because this will not increase the TOTAL assist gold. Remember that you can also gain an assist by healing the member that takes the kill, you dont always have to damage the enemy to get an assist.

3. There are certain items which get stronger off kills, such as Mejais Soulstealer, Sword of the Occult and Levithians. It is always better to give the kill to champions with these items, because they get two stacks for a kill, and only one stack for an assist.

4. Some champions have abilites that benefit from kills, such as Master Yi’s Ultimate, Akali’s Shadow Dance, Veigars Baleful strike, etc. and so it is better to give them the kill.

5. If a champion kills many other champions in a row, he goes on a killing spree. The larger his killing spree, the more bonus gold he will give when he dies (up to maximum of +500). This means that for every kill a champion gets he is worth more gold to the enemy when he dies. But if a champion has killed more than 7 champions in a row, his bounty does not increase. So it is always best to give kills to this champion, as this does not increase the TOTAL gold that the enemy team receives when they kill him.
Also, when a champion is on a losing spree, they give less gold. So when a champion is on a big losing spree, it is best not to give them the kill and so not end their losing spree, so they continue to give little gold.

Please remember at all times that it is always better to secure a kill when there is a chance that they might escape. All the above only apply when the kill is certain and there is a choice between who gets the kill.

Minion steal
1. Some champions scaled better with gold. It’s always better to give minion kills to them. The AD carry scales best with gold, and support the worst. This is why in the bottom lane every minion kill will go to the ad carry. Remember, however, that once a champion has full build (they best six items they could possibly have + all the elixirs) they have no more use for gold and so there is not point in giving them gold.
2. Certain champions have abilities that scales well with minion kills, such as Nasus’ q, Sion’s e and Veigar’s q. It is usually best to give kills to these champions.
3. Certain items scales with minion kills, such as Warmogs and Bloodthirster. It is best to give minion kills to champion with these items, until they are fully stacked.
4. Sometimes a player will only need say 50 more gold to buy a certain item and so they might ask you to leave them the closest minions.

Jungle monsters
1. When you kill certain monsters you get a buff, which makes your champion stronger. It is usually best to let the champion that benefits most from this buff to last hit the monsters. For example: blue buff on mages and red buff on ad champions.
2. Other than that, the same rules as for minion kills apply.
