(Bud-er-E-a) Especially nasty form of diarrhea that is a common after-effect of a night spent drinking Budweiser products. This condition usually results in watery, yellow-ish bowel movements and severe stomach cramps.

aka "The Bud Mudd" or "Mudd Slides"
Bud Light was on special last night. Cheap bastard that I am, I drank that crap and I've been paying for it with a terrible case of Budarrhea all day.
