Fuck-nut 

Fuck-nut; the rated R version of "loose cannon" is an insult implying that the recieving end is incapable of basic human thought, therefore indicating a need to be insulted. This is where "fuck-nut" comes in. Walk up to this "individual" and as if a magician saying abbracadabra, say it straight to their dumb fucking face.

"Excuse me kind sir."
"Yes my friend?"

"You are a bonafide fuck-nut!"
