Someone who plays Gears of War (a game for the Xbox 360) every waking our of the day and has decent skill, but gets the grenades every round and tags the first thing he or she sees (even if this action results in death, which it does most of the time). This type of player does not care about kills or points, they care about PISSING YOU THE HELL OFF as fast as possible. they are hated by both teams involved in the game and are generally avoided if possible.
OMFG, that FAG TAGGER just tagged me AGAIN! BOOM!!!
