When you have been eating greasy fast-food and have to shit really bad, but the toliet is too dirty to sit on so you bend over and fart, blowing mud all over the toliet painting it brown.
While at the red robin, I had diarrea and gas real bad. The toliet had pee on the seat so I bent over infront of it and when I farted I blew mud all over the toliet painitng it brown. Brown butt paint in da house! Booyaa!
