Drain tanking
The act of lifestealing (or using spellvamp/other forms of sustain in case of casters) damage done against enemies to tank their damage. Champions which do this are difficult to kill, especially in 1x1 situations, because they heal through all the damage done, and even if they don't do a lot of damage back, they can win the duel just because the enemy cannot burst them down quickly enough to prevent them from healing back. However, if their sustain is reduced or denied (because they are under CC effects or unable to attack), they can become easy to kill, since they tend to not have or to have less actual tankyness to fall back on. Examples of champions designed to be drain tanks are AatroxSquare Aatrox, WarwickSquare Warwick, and OlafSquare Olaf.

L

Lag
Slow response during the match due to high network connection latency.
Some players also refer to the slowdown due to an insufficient computer system as lag.
Lag specifically refers to the time between when information is sent and when it is received. This can be caused by a network latency, in which data is delayed between a user's computer and the game server, or by a slow computer. Lag most often manifests as "outbound lag", or delay between when a command is given and when it is performed. Lag can also manifest as "inbound lag", or a delay between when an event is registered on the server and when it is displayed on a user's computer. This causes "jumping", or the appearance that a champion's position, health, mana, etc. has suddenly changed.
Lag Spike
A sudden and often momentary period of severe lag.
Laner
The champion or player who occupies a certain lane during the early game.
Lane bully

Lane swap
A strategy of laners switching lanes to compensate a disadvantage. This strategy used to be very common in competitive games (and very rare otherwise) because it can allow teams to counter some Top icon top laners which cannot effectively lane against the power of a Bottom icon bottom laner and Support icon support. Recent changes make this strategy very risky, the bot lane has less durable towers, and first tower gold is highly contested.
Laning

Meta
metagame
The game's current effective play style, consisting of aspects such as lane setup, jungling, and team composition.
Metagolem
An incredibly strict build that can be flexed on a certain type of, or in more extreme cases, every champion, that dictates the meta by being unbelievably overpowered. The term is a portmanteau of the words "metagame" and "golem".
A now archaic metagolem that consisted of Warmog's Armor item Warmog's Armor, Atma's Impaler item Atma's Impaler, Frozen Mallet item Frozen Mallet, Trinity Force item Trinity Force, and Mercury's Treads item Mercury's Treads.
To a lesser extend this term also applies to a trend in early 2016 for many champions that were supposed to build squishy, to build tanky. This is because back then, items like Sunfire Cape item Sunfire Cape, Iceborn Gauntlet item Iceborn Gauntlet, and Titanic Hydra item Titanic Hydra, as well as the Grasp of the Undying mastery 2016.png Grasp of the Undying mastery, used to be overpowered. They allowed almost any champion to work with a tanky build because those items provided artificial sources of damage, with Grasp of the Undying providing health-scaling sustain and high base damage as well. A lot of champions that were otherwise supposed to build glass cannon started to build tanky. The most popular examples include Master YiSquare Master Yi, FioraSquare Fiora, EkkoSquare Ekko, FizzSquare Fizz, and even AkaliSquare Akali. Most of those champions had their base damages nerfed to encourage them to build glass cannon, and the aforementioned items were also nerfed to make them more expensive or do less damage, discouraging their purchase on non-tanky champions.

Off tank
A champion that has some attributes of a Tank (ability to soak damage, initiation ability, CC, etc.), but lacks in one or more areas.
Off meta
A champion being used in a completely different way from what is considered meta for them. For example, it can refer to going with a different lane than intended (e.g. jungle BrandSquare Brand, support Jarvan IVSquare Jarvan IV) or a different build (e.g. AD AhriSquare Ahri, AP TristanaSquare Tristana).
Sometimes the champions themselves may be considered off-meta if they are uncommon enough, even if they are played as intended. Examples include VolibearSquare Volibear.
Unusual strategies that are very rarely seen on most games. For example, going dual top instead of going with one top and one jungler, or playing a melee champion as your ADC.

Overextending
A champion moving too far in lane/enemy territory, which can open them up to sudden engages.
Overloaded
A champion which has too many tools or their kit, allowing them to do many different things at once; either because their abilities have an excessive amount of effects, or because their abilities are just too versatile. Champions like this can be considered difficult to balance due to that reason, as simple numbers changes are usually not enough to bring them in line with other champions.
This can also be applied to items; if an item is too versatile (either due to having many different stats, or effects, or both), it can be considered overloaded.
Overkill
The act of dealing (substantially) more damage to an enemy than is needed to kill him off.
Overtuned
A champion which has overbearingly high numbers on their abilities (base damage, scalings, range, missile speed, etc) or their stats (base HP, HP per level, base AD, etc).
An item can also be considered overtuned if its stats or the numbers on their passive or active effects are too high.

Stat check
Stat checking
A champion that wins trades just because it has superior stats, instead of because it outplayed the enemy or because it used a certain combo. Any champion can potentially be a stat check, but some champions are considered stat checks because due to how their kit works, they rely mostly or exclusively on stat checking to deal with enemy champions.
A champion can be a stat check because it simply has better stats (ex: having more max HP than the enemy), because it has a lot of a stat that directly counter the enemy (ex: having a lot of armor against an enemy that does fully physical damage), because it can heal more than the enemy can damage, or because it can reduce the stats of an enemy (ex: reducing the enemy's attack speed).
Stat stick
An item which either does not have an unique passive or active, or has one that is very weak. In either case, the item is considered useful mostly for its stats; indeed, most items which are considered to be stat sticks tend to have superior stats compared to items which have useful passives and/or actives. An example is old Phantom Dancer item Phantom Dancer, which did not had a 12% damage reduction passive, and was useful mostly because it used to offer 50% attack speed and 35% critical strike chance, which was superior to old Statikk Shiv item Statikk Shiv's 40% attack speed and 20% critical strike chance, allowing Phantom Dancer to compete with Statikk even though the latter had a lighting passive that did burst damage and waveclear. Phantom Dancer was even stacked, because the stats were just that high.
Steroid
A temporary, self applied, straight-forward ability that increases one's performance without tangentially altering it.
More specifically: an ability that provides an increase to a champion's base stats, or the part of the ability that does so.

Sustain
Sustainability

Sustained damage
A large amount of damage that is done over a long period of time. Essentially the opposite of burst. Despite the name, sustained damage does not always come with actual sustain (but most of time, will do). Sustained damage is considered to be better to deal with tanky targets, while burst is more effective against squishy targets.
SV
