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.”

The feeling of moist, itchy, clay-like fecal matter which remains in your anal cavity after sub-par wiping is the result of one having an extremely messy bowel movement and spending four to six hours perfroming physical activity in moderate to extreme heat. The aforementioned condition may or may not result in the dragging of ones bare anus on a coarse surface such as a carpet or snadpaper.
Jesus Christ, I took a massive shit before helping you move and spent my day scratching my mud butt.
