What is Necrodoucher?
Someone who cleans a dead woman's vagina with his tongue. Usually a prelude to sex with the corpse, making a necrodoucher oftentimes a full-blown necrophiliac.
An insult associating a disliked person with such an unspeakable act.
That asshole Bob is such a psycho, I bet he gets his jollies from being a necrodoucher.
