The reverse necrophilia is a sex position (usually woman is on top) in which the woman rides a guy so good, after he blows his nut, he falls into a deep slumber. The woman continues to ride, getting off on the fact he is limp, resembling a dead corpse. The woman can cum multiple times while her partner is asleep. If the man is not asleep the woman can not cum.
Brudduh, Katy made me bust a fat one, I don't remember much after that, I think she did The Reverse Necrophilia on me while I was out cold!
The word for bringing back the dead and having sex with them, often being used as a loophole in fanfictions or porn to not be associated to necrophilia.
