Mudslide in the canyon 

A person must first have diarrhea. This is the sexual act when said person poops in a woman's taint and allows it to slide into both the anus and vagina.

I heard Sheila got a mudslide in the canyon last night, it was pretty messy.

Mudslide canoeing 

During anal intercourse the male hits a nerve that causes the female to start shitting uncontrollably on the males dick, while the male continues to bang her using the shit as lube.

Amanda was taking it up the butt when suddenly she had the urge to shit. John then continued to bang and begin his journey of "mudslide canoeing" until he was satisfied.
