Usually happens during surprise anal, when a woman has not evacuated their bowels properly. You usually get a five second warning after you mash a turd with your meat stick. Then suddenly, she needs to shit, so you pull out and the tip of your penis is wearing a top hat made of poo.
"After Katie gave me a chocolate top hat, life was not the same. No amount of soap can ever clean me. I might as well throw my dick out."
