Groundnuts 

A word used to describe a man's crushed testicles.

Also used as a more extreme replacement of "Balls" in shitty jokes.

Formed from "Ground"- which is the past tense conjugation for the verb Grind, and Nuts, the slang for testicles.

(Threatening) You're gonna get Groundnuts if you you touch my Spaghetti Sauce ever again.

(Sarcastic) My Groundnuts probably weigh more than those chocolates.
