Flappers were a generation of young Western women in the 1920s who wore short skirts, bobbed their hair, listened to jazz, and flaunted their disdain for what was then considered acceptable behavior.
What does the slang flapper mean?
The slang term "flapper" may derive from an earlier use in northern England to mean "teenage girl", referring to one whose hair is not yet put up and whose plaited pigtail "flapped" on her back, or from an older word meaning "prostitute". The slang word "flap" was used for a young prostitute as early as 1631.
Why are they called flappers?
The term flapper originated in Great Britain, where there was a short fad among young women to wear rubber galoshes (an overshoe worn in the rain or snow) left open to flap when they walked. The name stuck, and throughout the United States and Europe flapper was the name given to liberated young women.
