Pumpernickel Finger-Gun 

A Pumpernickel Finger-Gun is a sexual act that involves anal sex and fingering. It commonly occurs when a Male and Female are having Anal Sex and the Males penis gets stuck in the Females sphincter.

Then, the Male has to use his fingers to get his penis out of the Females sphincter, which causes the Female to release her bowel contents all over the Males finger.

It is a very messy process.

"Bro, I was fucking Stacey last night and we had to do the old Pumpernickel Finger-Gun!"
"Go... Go wash your hands, David."
