There is no shame in dying.

There is no shame in dying, and at certain times it can be hilarious. If you've got nothing to do during setup time in TF2, bind your K key to either "kill" or "explode" and press it, for glory.
And if you attack, and win, give the losing team something to wipe their tears with. Jump off a clif, run into a wall, fall down some stairs or simply just explode. It's your choice, as long as you don't value your virtual life over hilarity.
