Sloppy Joanne
When a male is giving a chick anal, but before he proceeds to penetrate her, she takes a huge mother fucking shit, and then without wiping her asshole, the male inserts his cock and uses her shit as lubrication
Person A: "There was no lubrication"
Person B: "How'd you fuck her then, man?"
Person A: "I just gave her a sloppy joanne"
