The unfortunate result during anal sex if the person doing the receiving does not properly prepare for the event, ie douching with a colonic or an enema, something, ANYTHING, for God's sake.
His date knew that anal sex was going to happen, but failed to prepare, and after a few minutes a Malibu Mudslide cut their evening short.

After rigorous anal sex and a happy ending with a partner who has loose stools, results in a blended mudslide running down their leg.
Derek wasn’t feeling well, but was still willing to have sex, and we ended up making a blended mudslide down his leg.

Somewhat similar to the cleaveland steamer only while tittie-fucking a girl you simutaniuosly take a hot staeming shit so it is smeared all the way from her boobs to her navel (ewwwwww!)
I gave that girl such a bad Steaming Mudslide that it looked like she used sewage on a slipping slide!!!

It is where you are trying to take a shit but can't get to the toilet in time. The shit explodes out of your ass and shit hits the side of the toilet and runs onto the floor.
Grandma was quick walking to the bathroom again. I bet there is a 618 Mudslide in that motherfucker!

When you are in Philly and eat two Philly cheese steaks from a street vendor and fly to New York City and shit in the plane 20 min in.
You start out by shitting on someone's chest, you then sit down on the shit and slide down the person's body. An anal motorboat is optional.
"Hey Brad, I heard you gave Joe the Samoan Mudslide. "
"Yeah, he's never gonna get that shit out of his chest hair. "
