A Bumble Nut is other wise known as a small ball of faeces that has not been wiped properly and sticks to the hairs around your anus, and is left so long it has gone hard. The name derives from Bum-Ball-Nut but recent accents in recent times have thus changed this to Bumble Nut
In school we went swimming and my mate Benyon tried to change into his trunks but his underpants were caught on his Bumble Nuts.

My mates girlfriend made me a Bumble Nut Sandwich for lunch last week.
