bunk: as in so wrong
"dude, that was just bunk"
wow! to me and others here bunk is a good thing. it's booty. "that girls got bunk."
HAHAHA serious? its a "wrong" to us or nasty....depends.
Never heard it in this context...I've heard "That's so much BUNK you could make a bed." corny yes, real expression unfortunately.
it comes from people saying someone has "spunk." but bunk means butt. among many other things i'm sure.
