I have been, ONCE, on the receiving end of someone calling me
“numbnuts”, and I considered it the WORST kind of man-to-man
insult imaginable. Michael Steele, IMHO, was far worse than anything I’ve seen or heard about from Reince Priebus.
Priebus, though, has started to get lots of flak from disgruntled Conservatives,so maybe he’s proved he’s just as feckless as Steele. We need somebody stronger than both of them. At least Priebus hasn’t proposed integrating rap “artistry” into the GOP outreach.The only difference between them may be that “leadership” is all that much more urgent now.
I get that it's a bad insult, but I'd always thought of it as just another way of saying "stupid" or "jerk" or "lame," not as having a specific sexual meaning.
