A new trend that I invented during an AIM conversation to kill a silence. It is the new solution for all your problems. Known to cure anything except AIDS which it only slows down.

Punching yourself in the ass is only for sexual related problems. Punching yourself on the ass is for all other purposes

What your eye hurts? punch yourself on the ass! You have a headache? punch yourself on the ass! You feel light headed? punch yourself on the ass! Your friend is acting gay? punch yourself on the ass! (beware--this may be a little suggestive to the person if they are truly gay)
