Do you teabag enemies? Do you throw away all your ammo and crafted items? Or do you just use your gesture over and over?
For me, I go and pick up my downed teammates and teabag them.
I shoot my remaining Flamethrower fuel into the air to declare my victory. If I have no fuel left, I do nothing, really.
Teabagging is really lame and stupid, IMO.
My second favorite is running up to the last dead enemy and lighting myself on fire with a molotov.
Or is that immature also? IT'S A GAME!
I'm wondering if all those t-baggers enjoy when the opponent t-bags them, when they're defeated - cause no-one wins always
