The sensation of having a greasy and unwipeable ass usually occuring after consumption of large quantities of fried or fatty foods. A result of oily anal discharge, leakage, or extremely tacky fecal matter. Often accompanied by, or preceded by, 'The Itis.'
I ate two plates of ribs and a half pound of fudge last night. I keep wiping my ass today but I just can't shake this Mud Butt.

Feces. Made famous by a hilarious episode of South Park where (SPOILER!) Stan makes a dookie in the school's urinal and is punished for it

An aninal indegenous to water with a lifespan of about 2 or 3 minutes. Usually dark brown, but can vary to hues to mustard yellow. Where it smells horrible, the odor can usually be alleviated by flushing the toilet.
