Knockin’ Chunks 

Anal sex with someone with a filthy stank ass fart box. Usually results in shit dick and knob dob.

Man I put it to that homeless dude behind the dumpster but I tell you it was knockin’ chunks.

I banged the chick from the food delivery. She’s as DTF so I hit it from the back and was knockin’ chunks.
