Sometimes it seems that stupidity and foolishness pervade everything. Perhaps that's why we have so many words for it. To take a hundred-odd:

airhead; asinine; ass; bilge; birdbrain; birdbrain; blockhead; blunder; blunderbuss; bonehead; boob; booby; brainless; brute; butthead; chowderhead; chucklehead; chump; clod; cluck; clunk; daft; dimwit; dingbat; dingleberry; dingus; dip; dodo; dolt; donkey; doofus; dope; dork; drivel; dull; dumb; dumbbell; dumbo; dum-dum; dummkopf; dummy; dunce; dupe; fathead; fatuity; featherbrain; flibbertigibbet; fool; frivolous; fuzzyheaded; gaga; goof; goofball; goon; half-wit; headless; howler; idiot; imbecile; imbecile; jackass; klutz; knucklehead; lamebrain; light-minded; lout; lummox; lumpish; lunkhead; meatball; meathead; moron; mutt; muttonhead; nimrod; nincompoop; nitwit; noodle; numskull; oaf; obstinate; palooka; pinhead; prune; ridiculous; schlep; schlub; schmo; schmuck; schnook; senseless; sheepish; silly; simple-minded; sodden; stupid; thick; thickhead; thick-witted; tomfool; vacuous; woodenhead; yap; yo-yo.

This week we'll enjoy a few more sophisticated words in the same vein.

unasinous – being equally stupid.

Here were representatives of three different, unasinous points of view, each deeply opposed to the others, and yet all attacking her!"
– David Brin, Earth

So go your ways, you Uncivil Ecclesiastics, Inhuman Divines, Dedoctors of morality, Unasinous Colleagues, Egregarious air of Issachars, most wretched Vindices and Indices Academiatrum.
– Thomas Hobbes, in his decades-long debate with scientist John Wallis. (Hobbes may have had the better of the words, but Wallis had the science.)

flibbertigibbet

I have decided to do a Wordcraftjr Theme on some of these great words that mean 'stupid.' However, I have a question. Some sources say that flibbertigibbet means "A silly, scatterbrained, or garrulous person," while others say it means "a female fool."

Is "flibbertigibbet" more associated with women?

So far as I'm concerned, it definitely refers only to women. 1549 was most certainly a sexist time.
