It's when you don't wipe your bum good enough after taking a poop. Your bum can get poo crusties and make your asshole itch.
I've got a bad case of butt rust this morning after all that drinking and pooping I did last night. Poop.

Get the butt coffee mug.A kind of music popular amoung tweens esp. in the midwest and is usualy found in the alternative rock section of a music store. Butt rock bands usualy have perdictable percusion break downs, simple bass lines, simple gutar riffs and overly emotional/ semi romantic lyrics. The trade mark of butt rock is the straind vocals that make the sinnger sound like he is constipated. This is where "butt" rock gets its name. Examples include: Hinder, Creed, Matchbox 20, three doors down, avenge seven fold, ect. Its is possable for a band to resemble butt rock but not actualy be butt rock. I.E. staind, coldplay, foo fighters.
