Liptonboy

A guy who teabags every dead character in a game whether they made the kill or not. Usually used to describe online games but is not exclusive. This behavior is especially during a LARP for obvious reasons.
Also a war crime if done in actual combat

Wow! Timmy is really good at Call of Duty! Naw hes just a Liptonboy.
Or
If that fraking Liptonboy teabags me one more time I'm going to shove this foam halberd where the sun dont shine!
