The left over poop smear that sticks to the bottom and side of the toilet after a good dump. So thick and sticky not even the strongest flush or the most powerful stream of pee will remove it. Similar to the left over peanut butter that remains on a knife after spreading it on a piece of bread.
Man, that toilet is covered in Porcelain Butter. It will take a tall glass of milk just to wash it down!
