blow monkey chunks 

A variation on blows chunks. Origin unknown. Appears to imply projectile vomiting of diced primate, but that is likely too literal an interpretation. Often used to indicate extreme dislike.

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.
