Its source is an English expression meaning "Girl midget."
The name Gidget ranked 3647th in popularity for females of all ages in a sample of the 1990 US Census.
Though this name appears on the 1990 U.S. Census lists, it is used by only a small percentage of the general population.
This was the nickname of the naive, petite title character of a 1959 Hollywood film (her actual name was Frances Lawrence). She was played by Sandra Dee. The immense popularity of this beach movie spawned sequels on both the large and small screens until as recently as 1986.
