It's where you with a group of close friends and when the pussy friend leaves the room those who remain figure out a code word to say when they get back. When they get back someone says the code word and everyone jumps on the pussy friend holding him down while another friend punches him repeatedly in the ass until his ass goes numb or "dead".

One friend - "Pickles"

All but pussy friend - let's dead ass him!

Man we dead assed the shit out of him so bad.
