banjo butt 

A term used to describe a woman who has a slender back and a narrow waist but has unusally wide hips and out of proportion to the rest of her body.

She's cute but she's got a real banjo butt crammed into those jeans.

A flat, puddle, pancake or banjo shaped ass caused by excessive time spent posting online.

That poor fool on my motorcycle forum with 100,000 posts must be a real Banjo Butt.

Butthole Banjo

When a person has a string tied to their big toe and the other on to a butt plug inserting the butt plug in their anus, and proceeding to play a one string melody while they pleasure themselves.

“I was astounded after walking in on Johnny playing the Butthole Banjo in my bathroom.”
