The little bits of poo left behind after a flush. Butt Crumbs will generally swirl around as the toilet fills, but often settle in the bottom eventually. Phantom Butt Crumbs also exist - they tend to show up after the toilet fills halfway, so even after you check there is still a chance they will show up. Butt Crumbs are most common after eating a big salad or Chinese Buffet, but also occur often during an illness.
also known as 'leavings' by those more cultured.
'dude, did you have a salad today?'

'must have been phantom, i waited after the flush for like a minute.'
