Necrosodomy 

An act of rape upon a dead body. While engaging, the sodomizer commits an act of necrophilia. Usually followed by horrendous odor.

It is often ensued with questions of legality...

"Is it really Rape if he's dead."

"Oh shit this orifice is cold."

Dude, you should cover that shit up when you're done.

"Why?"

Because Necrosodomy is illegal man.
