Mudbutts 

When you have uncontrolable bowels...aka Diarrhea.

I went to Pancho's Mexican Buffet, and before I could get to the table, I have an onset of the mudbutts... I seriously shit my pants.

Mudbutt

When you take a shit and there’s literally more poop on the toilet paper than there is in the toilet, and the poop is extremely sticky and thick (almost tar like)and impossible to clean off your asshole without scrubbing intensely in the shower. Usually happens when you eat too much junk food.

P1: “WTF took you so long in the bathroom? Were you writing a novel or something?”
P2: “Sorry, had a bad case of mudbutt. It was like the labrea tar pits down there.”
P1:”Maybe if you didn’t eat all those god damn Doritos every day and ate a fucking salad once in a while, you wouldn’t have that problem.”

mudbutt

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."

I got mudbutt from eating chilli and spent a long time on the toilet.

GOOD LORD, IT'S MUDBUTT!!

Explosive diarrhea from "Chappelle's Show." First on the skit, "First black man to use white toilet"

"I had gone out to buy a roast beef sandwich from a boy who used to sell them up front. A little bit later, I could feel a bubblin'. Little did I know, that roast beef sandwich would change my life."
