She couldn't wait till the elevator doors closed because she had a bad case of "Butt-Crumbs"
small specks of poo that fall down on to the toilet seat while wiping. Particularly visible on white toilet seats (but carpets do an excellent job of concealing them). Usually observed among those with hairy cracks and high-fibre diets.
Father: Yes, why do you ask?
Son: I saw some butt crumbs on the toilet seat.
also known as 'leavings' by those more cultured.
'yeah, howd you know?'
'you left a bunch of butt crumbs in the toilet'
'must have been phantom, i waited after the flush for like a minute.'
also 'when you came to my apartment, you left butt crumbs, in the toilet...Annie are you ok? are you ok Annie?'
