When playing an online shooting game, it is the act of killing someone who is distracted by being already engaged by another opponent. It is often used for killing an opponent of superior skill, or to steal kills from other players.
ie: Two players are fighting 1 on 1 in a game, and some Gmoney comes flying in from behind and sidebusts the one guy from behind, stealing the kill.
