gank v.

by 2000 as the verb that indicates the situation of many players or NPCs simultaneously attacking one; gamer slang, perhaps borrowed from hip-hop and drug-abuse slang (where it is attested by 1995 in the sense of "to rob, to rip off"); perhaps by 1990 in sports jargon. Of unknown origin; perhaps ultimately based on gang (v.). Related: Ganked; ganking.
