Biffon

The region between genitals and arsehole, also known as the perineum. This gets its name as it’s the part of the body that the balls ‘biff-on’ during sex.

The slapping of my balls against the biffon made a lovely rasping sound.

Biff Jerky

The act of receiving a Handjob while your partner is bent over and farts in your face.

Thanks babe, I really enjoyed that Biff Jerky last night!!

Biff

A gust of steamy air that speaks in between your hairy cheeks.
