it's basically being sexually attracted or turned on by corpses. people could either fantasize about them or they'll have actual physical contact with it.
it's kinda weird and creepy and illegal in alot of places i guess.
However, here in the US, there are no Federal laws against necrophilia, and only nineteen out of fifty states have anti-necrophilia laws.

probably derived from greek 'necro' having something to do with the dead and 'philia' meaning something to do with sex. Therefore meaning shagging the contents of a sarcophagus or fantacising about the aforementioned act while masturbating or something like that.
