the dust that resonates around shit in the toilet when you forget to flush and it sits there for a while. Most visible when you flush after the shit has been there for a while.
Eric is such a douchebag, he forgot to flush and now the bottom of the toilet is covered in poop dust.

Poop dust is what comes out when you fart. The tiny particals of poop make it stinky. Some farts have more than others.

The tiny particles of feces that settle at the bottom of the toilet bowl after only flush when the original excretion was in the form of diarrhea and more flushes were needed to rid the bowl of its presence.

Ah man! the other day I farted and I thought for sure it was gonna be wet but it turned out to be a little bit of poop-dust! I was lucky

a nasty ass bowel movement that covers everything in feces and poop dust, much like an ass explosion of diarrhea or a bad case of swamp ass. seriously entertaining !!!
The bathroom at work smelled like boiled dinner, I knew immediately who had dropped the poop dust bomb in there !!!
