A white person who is sexually attracted to or amorously involved with a so-called Negro; usage circa 1960s.
Etymology: The word was current in the early to mid-1960s, before the black power movement replaced the word "Negro" with "Afro-American" and "Black" in polite conversation. The word is featured in the title of Guy D. St. Lazare's 1966 pulp novel "The Young Negrosexuals".
One who has no discernable sexual preference whatsoever. Generally, nihlosexuals are virgins, have not masturbated or will not reveal it, and show no sexual or romantic interest in any human of any sex, animal, plant, or mineral.
"I think Jeff's gay." "No dude, he's just a nihlosexual. He just doesn't care."
Someone who is sexually attracted to dead people(most likely ranging from the time they died to up until they are 2-3 days bernie). This type of person may often have the intentions of having sex with the corpse(i.e. necrophilia).
Jim: Did you see that one goth-looking guy who attended your cousin's funeral a week ago? I noticed a questionable look in his eyes as he was looking at her in the casket.
Eric: The fuck?! Don't be a fool! He was just mourning like everyone el... Oh yeah THAT guy. Hmm yeah I also noticed something suspicious about him. By the look in his face, he was definitely not mourning. He was also staying in front of her a little longer than us and the other mourners and he almost looked like he was about to hump the casket.
Jim: So all of this indicates that he's...
Eric: Right! That he's a NECROSEXUAL.
Jim: I thought as much. There's some pretty sick fucks out there in the world.
