The least a human being has to do to exist is to be ejaculated from the tip of a man's penis into a vagina: Hence, a "fuck nut". A fuck nut is a person with the least amount of intelligence it takes to exist as a human being and nothing more. i.e., they are only as smart or intelligent as they were first squirted-out of their father's nut sack.

Backstage slang: The small square-headed nut on the side of a C-clamp used to hang a light from a bar. Secures the light so it won't swing side to side. So called because they are easy to over-tighten, snapping the nut and making the clamp useless.
Stagehand: Fuck! I busted the fucking fucknut!

Lead Electrician: *sigh* get a new clamp from storage and swap it out... fast.

One who is "hyper-stupid." Or one who is more stupid than stupid itself: hence a fucknut.
