The sprinkles of fecal matter, rolled up tissue and odd arse crack pube that is often found left on the back of the toilet seat post-poo.
Usually left behind by an over-enthusiastic wiper.
(Often confused with Chuff Nuts
which are bum crumbs that remain attached to the crack hair)
Yeh I noticed I'd left a shit-ton of bum crumbs behind; looked like someone had been eating a chocolate biscuit over the back of the bog
Ah fuck! Dave's left a load of bloody bum crumbs around the toilet again. That guy needs to stop wiping his arse like he's trying to polish his Rusty Sheriff's Badge
. Dirty bastard!
