muddy waterfalls

Sloppy shit! The kind that runs down your trouser leg if you lose control. Usually after dodgy seafood, or meat with a slight 'oh that tasted weird'!

That lobster bisque must have been off. I've got the muddy waterfalls...

When one urinates through the legs of another person who is defecating.

Pisser: "Bro, I really gotta piss!"

Pooper: "Dude... I'm taking a shit"

Pisser: "Whatever bro, lets muddy waterfall!"

When a man is sitting on the toilet taking a steamy poo while the woman sits reverse cowgirl and bangs him hard while taking a piss.

Man, the other night when I was banging my girl Kansas Muddy Waterfall style while I was taking a massive shit, she pissed all over me!
