Butt-Fucking Ugly

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?
