frumpkin
A variation of the blumpkin, this sex act occurs when a women is sitting on a toilet defecating and simultaneously performing oral sex on the gentleman standing in front of her.
Lisa didn't know why, but after discovering what a frumpkin was she had an undeniable urge to perform one on the office custodian in the handicapped stall of the public restroom.
