wisecrack

'Wise' in American slang did not mean learned or sagacious. It meant insolent, presumptuous, too smart for your own good. 'Don't get wise with me' was a warning. 'Wise guy' was an insult before it was a mob title. This was the 'wise' that entered wisecrack — not the wisdom of Solomon but the impudence of a teenager talking back.

'Crack' had meant 'a sharp remark' in English since the fifteenth century. Shakespeare used it. A crack was quick, sudden, and loud — like the sound it described. American English combined the two elements around 1920, and the word appeared in print by 1924. A wisecrack was a joke delivered with excessive confidence, a remark that was smart in both senses — clever and mouthy.

The wisecrack became the signature verbal gesture of 1930s and 1940s Hollywood. Groucho Marx, Mae West, W.C. Fields, Humphrey Bogart's characters, and every hard-boiled detective in every noir film spoke in wisecracks. The form suited the Depression: brief, sharp, defiant, spoken by people who had nothing left but their nerve and their timing.

Wisecracking declined as a dominant comic mode after the 1950s, replaced by observational humor, absurdism, and irony. But the word survived. Stand-up comedians still deliver wisecracks. Political commentators wisecrack on cable news. The American impulse to talk back to authority in one fast sentence has never gone away — it just found new stages.
