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.

Similar to motor-boating, mud ruddering involves grasping each side of the buttocks, gently spreading the cheeks and placing one's face on the poop shoot; then shaking the head back and forth as if saying "no" while proceeding to make a motorboat sound.
