[quote name='utopianmachine']I've played a little of Halo, but why is it called tea-bagging? I get what tea-bags are, but isn't it just crouching or something?[/QUOTE]
You know how you dip tea bags in and out of the mug?
Well, balls kind of look like tea bags, so when you kill someone, you dump your virtual balls in and out of the enemy's mouth you just killed to piss them off. This is called "tea-bagging".
