effluence

Poo, shit, crap, feaces, basically what ever comes out of your arse (bottom, behind, anus, bum-hole, poo-poo).

Can also be used as a term to describe the way in which someone is talking...

...The Super bowl, twin turbo, uber suction excri-toilet will safely and quietly remove your effluence even before you've managed to pull your trousers up!

The words exiting Roger's mouth were so foul, it was a constant stream of effluence...
