When two people are having anal sex and the person pitching pulls his penis out of the other one's rectum to find a large glob of santorum hanging from the end of his rod.
I probably should have expected it because we'd gone out drinking all night then eaten that greasy midnight pizza over at Cosmo's, but when we got back to the apartment she let me do anal on her and when I pulled out of her she left a big mushroom-cap hanging off the end of my rod.
