Meaning "requiring or exhibiting courage" is from mid-13c. Also in a bad sense, "audacious, presumptuous, overstepping usual bounds" (c. 1200). From 1670s as "standing out to view, striking the eye."

Archie, British World War I military slang for "German anti-aircraft fire" or the guns that produce it (1915) is said in contemporary sources to be from the airmen dodging hostile fire and thinking of the refrain of a then-popular music hall song.
It's no use me denying facts, I'm henpecked, you can see!
'Twas on our wedding day my wife commenced to peck at me
The wedding breakfast over, I said, "We'll start off today
Upon our honeymoon."
Then she yelled, "What! waste time that way?"
[chorus] "Archibald, certainly not!
Get back to work at once, sir, like a shot.
When single you could waste time spooning
But lose work now for honeymooning!
Archibald, certainly not!"
[John L. St. John & Alfred Glover, "Archibald, Certainly Not"]
a complicated word of uncertain history. First attested late 15c. in the sense "lewd person" (of either sex; since c. 1700 applied exclusively to women); probably [Middle English Compendium] from Old French baud "gay, licentious" (from Frankish *bald "bold" or some such Germanic source; see bold), despite the doubts of OED. The 15c. English word perhaps is a shortening of baude-strote "procurer or procuress of prostitutes" (c. 1300).
For the French sense evolution from "bold" to "lewd," compare Old French baudise "ardor, joy, elation, act of boldness, presumption;" baudie "elation, high spirits," fole baudie "bawdry, shamelessness." The Old French word also is the source of French baudet "donkey," in Picardy dialect "loose woman."
The second element in baude-strote would be trot "one who runs errands," or Germanic *strutt (see strut (v.)). There was an Old French baudestrote, baudetrot of the same meaning (13c.), and this may be the direct source of Middle English baude-strote. The obsolete bronstrops "procuress," frequently found in Middleton's comedies, probably is an alteration of baude-strote.
