Experience, the points that raise your level. Minions and kills give it; two allies standing near the same minions split it.

what you type
dont take my xp
in full english
Don't take my XP.
the context
"xp" or "exp", never the full word. "dont take my xp" is the laner's complaint when an ally shares the lane's experience and delays their level 6; "share xp" is the same fact as an instruction.
