A term used to describe an incredibly ugly person; someone you'd have to turn around to
fuck. For
people who
aren't into anal, this is somewhat drastic.
Can also be shortened to "butt fugly".
Robin: Dude, look at the chick! She's so butt-
fucking ugly!
Oliver: I dunno, man, I think I'd just paper bag her.
James: Hey, fuck off, dude! That's my
sister!
Oliver:
Family resemblance, eh?
