When you go to the toilet and a big ass soft serve shiat and you use a whole roll of toilet to clean your funky a$$; taking a huge "pudding" type shiat; Normally smells like big Punn took that shiat;

When you have a problem and cant control your shit, it comes out of your butt crack and you feel a warm sensation. the aftermath can leave dingle berrys, depends on the amount of hair you have !!!
stacie had a mudd butt all last week, no pad or tanpon could help!! she had to cut off her dingle berrys from the intense amount of hair on her ass!!
