Mackin' the Slit
Stabbing someone with a knife and then using your junk to poke their open wound like it's a snack. One person gets a face full of cum and the other gets a face full of embarrassment.
Bro stabbed me in the gut and then used his penis like a French fry stick.
At the knife fight, I got macked by the slit and my guts were on the floor.
He stabbed me and then took a dump inside my wound. I died.
