So there’s fucknut which is just your run of the mill dipshit.
Also, not sure if this counts but my dad used to be a tennis buff and one of his tennis playing buddies was not very good. He also had a tiny, itty bitty fuse. Kind of comic in retrospect. Whenever he’d make a bad shot he would scream at the top of his lungs “fuck fuckers fucked!!”.
I use the expression to this day.

Thanks very much! "fucknut" was not in fact in the last edition, but I've already drafted it for the new one. The earliest example I have is 1980.
