While playing Halomultiplayer, after you kill an opponent, you stand over their body and repeatedly crouch over them. Thus looking like you are tea bagging them. Good for a laugh, especially if the player gets all pissed off.
latin: coleus gustatus
In this simple fetish, the man repeatedly dips his testicles into the open mouth of his lover or passed-out friend, in a motion similar to dipping a tea bag into a cup of hot water.
