Bavarian Mudslide
After anal sex, sucking the jizz out of the anus.
After getting rammed up the ass, Shane asked for a Bavarian Mudslide.
Bavarian Mudslide
While having diarrhea, you take a shit on someone's chest (preferably a female so the breasts are utilized as a canal) and then the person stands up. Allowing the runny defecate to act as a mudslide, running down the torso.
I was on a cheap domestic beer binge and your mom let me demonstrate a Bavarian Mudslide on her for the party entertainment.
