I saw Nekromantic in a big screen at a "fucked up artsy european movie" cycle in College. Lots of pretentious alternative girls who will blow you if you've ever heard of Jodorowsky, so I used to go to the showings every week, even if most of the movies were pretentious crap. Anyway, Nekromantic about a guy who works in a morgue and likes stealing corpses and using them for threesomes with his girlfriend. Then the girlfriend loses interest so she kills the guy and brings him back as a zombie to further fuck him (or was it the other way around?). The movie is relatively fucked up until the very end, in which the guy is seriously injured and begins wanking, turned on by his own death. He wanks and he wanks and he wanks and he wanks until he starts cumming blood and more blood and the blood starts coming out like a hose and then his cock starts falling apart and he's still furiously wanking and the pieces of his cock are flying off as the blood continues jumping in great quantities. You could hear collective sounds of disgust as the audience, including myself, began walking out at this point.
