A thin "dust-like" appearance to leftover poop in the bottom of a toilet still visible after someone has flushed. Typically bean dust is most commonly found in public restrooms where various people of all walks of life take dumps.
OMG! Could somebody tell Tina to be sure and give a second flush so I don't have to see her bean dust in the toilet.
