The loose, watery diarrhea that occurs after you eat some bad koshari; can be thought of as North Africa's version of Montezuma's revenge.

excessive diarrhea; made popular by Dave Chappelle on "Chappelle's Show," in such skits like "Ribs" and "Black Man on a White Toilet". Could also be spelled "muddbutt." And Crabs: A tiny bug like creature that will infiltrate the pubis maximus, and lead you to isle 3 at the local pharmacy for some blue ointment.. except in this case you’re not going anywhere because the mudbutt, so you’re screwed.
Michael: I can’t come into work today because I’m sick. *ahhhh*
Michaels Boss: Yeah I could hear it, it sounds like you have Mudbutt Crabs, you should stay home, like forever, we don’t want you here with that bullsh*t. Everyone at work discussed it annnnd everyone thinks it’s best that you don’t come back, so... you’re fired.
