The remainder of goop left over from a massive shit that plopped into the toilet, causing the poo, pee, vomit, bacteria, menstrual blood, and whatever else is in your toilet at the time to spew up into your anus, leaving you with a dripping mixture of FUN.

Jane: Damn, I know I should have swallowed them ropes.

A sexual act whereupon a man is fucked up the ass and then shits the cum and feces mixture onto the chest of his partner. The partner is then laid out in the sun with the mixture spread thin across his chest. As the sun dries the mixture, it becomes crusty. Then you punch him in the dick.
