When you fuck a girl up the ass and then she takes a shit all over your dick. If you ejaculate it turns into an snowy avalanche

Instead of wiping after taking a dump, you slide your ass on a body part of an unsuspecting individual. Those with hairy legs are optimal targets.
John gave Gunther a mudslide while he was sleeping, and Gunther put him in intensive care when he woke up and found it.

When you leave shit streaks in the toilet bowl after taking a dump and flushing. This is usually caused by heavy consumption of light beer causing your stool to be loose but not quite diahrrea.
I left a mudslide in Bill's toilet this morning after drinking a lot of Natty Light yesterday. Sorry Bill.

The Mudslide is a variant of the Balderdash sex position.
The Mudslide involves both parties covering their entire bodies in lube. The bottom lies spread eagle on the bed, and the top takes a shit on their chest (or puts shit on their chest). The top then goes across the room, faces the bed, and makes a running leap for their partner, penetrating them in the process.

When you are receiving head from a girl in a situation in which she is on her knees and you are standing up, you take her head and shove it close to your stomach, then you shit all over her torso.
