Poop. Shit. Crap. Fecal Matter.

Screaming Jesus on a ferris wheel! There's bum paste everywhere!

bumpaste 

An exceptionally unpleasant consistency of diarrhea, noted for its stickiness and slight remnants of solidity. A sour mash besmirching ones undergarments.

"My guts are bloody awful after that curry, I've been making bumpaste all day."
