All of this terminology. I don't even loving understand what anyone is saying.
laning:
mia/mis/ss = the person is missing from their lane.
b = go back, has been substituted with annoying as forget retreat pings.
push = Forget last hitting and try to destroy enemy minion waves as quickly as possible with or without wasting all your cooldowns/mana, with destroying their turret as a goal.
bot = The bottom/right lane.
mid = The lane that goes through the middle of the map.
top = The top/left lane.
jungle = Everywhere that isn't a lane or the base
ward xx:xx = An enemy placed a ward that will expire at xx:xx
baron = The strongest neutral monster, identified by a large red icon.
drag = The dragon, on the opposite side of baron.
gank = Enter another lane to kill an unsuspecting enemy
farm = Get as much gold as possible from minions
champs:
gp = Gangplank
lb = LeBlanc
mf = Miss Fortune
tf = Twisted Fate (if someone says kill tf, they don't want you to kill an item)
Everyone else either gets called by their full name or a shortened form of it.
items:
tf = Trinity Force (if someone says get tf, and twisted fate is not in the match, they probably are telling you to get this item)
ie = Infinity Edge
pd = Phantom Dancer
AA (staff) = Archangel's Staff
ga = Guardian's Angel
gb = Hextech Gunblade
razor = Madred's Bloodrazor, not the other one.
roa = Rod of Ages
bt = Bloodthrister
other:
CC = Crowd control. Slows, knockbacks, knockups, stuns, taunts, snares, silences, blinds, and suppressions.
cs = Creeps slain, or whatever. How many minions you've killed.
ult = Your R ability. You can see if allied ults are ready by the green icon by their character portrait on the left side of the screen.
If there's anything else, I either forgot it or it's not a LoL term.
