Getting relentlessly targetted by one or many players in a fighting game
Usually said in multi-player fighting games such as Super Smash Bros. or Rumble Fighter, getting kamped happens once you have done cheap moves torwards other players in the match, these cheapy moves can vary depending on game but one sure way to get kamped is by "vulturing" which is getting an easy kill off a weakened opponent whilst they are preoccupied in a fight.
Player 1: *gets vultured by Player 2*
Player 1: "... Kamped."
OR
Player 2: "I just got Kamped... reported."
