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.”

"Oh my goodness, that Thai food gave me a severe bout of the mudbutt!"

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!!

mugnut 

A mild expletive, to describe someone that is a bit of an idiot, plum or wally. Can be used for any kind of situation where a daft decision or comment is made. Can also be shouted in a gruff or silly voice to add a little comedy value! :)
