A term heavily used in the first-person shooter multiplayer online game "Battlefield 2." Teabagging is referred as, upon a successful kill of another player, crouching over the head of the victim's dead body as they lay on their back (dead); and doing so repeatedly in a "teabagging" motion. This act is to shame and humiliate the victim player, and usually incites anger and violence. This act is not unlike dances performed by football players after a touchdown.
"John began teabagging Jane after his hand grenade blew up next to her head; this angered Jane greatly."
