Mackin' the Slit
You cut someone open and then stick your dick in their hole like you're doing a weird kind of foreplay. It’s the rudest way to win a fight.
I cut my buddy open and then shoved my penis in his slit like he was a sandwich.
She stabbed me and then used her cock as a meat thermometer.
He stabbed me, then put his junk in my wound. I had to go to the hospital for my dignity.
