i didn't clean my butt well after having explosive diarrea, and now i have a bad case of butt crusties.

The tiny specs of crunchy looking balls of sweaty dirt that fall off on to the back rim of the toilet seat, from just above your ass crack. Similar to dingle berries, these crusty little dustings collect usually after wiping occurs.

A flaky substance that comes out of the butt after u don't wash it for a month.
Good on spaghetti also known as parmesan cheese.
