look up any word, like thot:
 
1.
little pieces of poop, which look like crumbs, that is left behind after the primary poop has been flushed.
My roomate left alot of poop crumbs at the bottom of the toilet.

2.
The remaining shreds of poop that are hard to get to after wiping from a nice dry poop
-hey chase, how was your poop?
-good, but i think i'll find a few poop crumbs a little later
-that's too bad. maybe you should have wiped better
