2. (colloquial, chiefly historical) A young woman, especially when unconventional or without decorum or displaying daring freedom or boldness; now particularly associated with the Jazz Age of the 1920s.Examples: "I paid violent and unusual attention to a flapper all through the meal in order to make you jealous. She's probably in her cabin writing reams about me to a fellow-flapper at this very moment."; ""Now," said the young man cheerfully to Ardita, who had witnessed this last scene in withering silence, "if you will swear on your honor as a flapper—which probably isn't worth much—that you'll keep that spoiled little mouth of yours tight shut for forty-eight hours, you can row yourself ashore in our rowboat.""; "Concern—and consternation—about the flapper are general. She disports herself flagrantly in the public eye, and there is no keeping her out of grown-up company or conversation."colloquialhistorical
