/gwæn li/
Derived from Han Lee, a person says it to subtly, but sarcastically, acknowledge a bad call from a teammate.
(A player could've shot the goal)
Second Player: "Pass it to me I'll make it"
*Misses*
You: "GWAN LEE!"
CS:GO Teammate: "He's in CT Spawn!"
(He wasn't in CT spawn and you died.)
GWAN LEEEEEEE!
