Charleston
dance style characterized by side-kicks from the knee, 1923 (as title of a song), 1925 as a dance, from the U.S. city of Charleston, South Carolina, which was named for King Charles II of England.
Whether the Charleston (dance) has come to stay or not, it behooves every open-minded hostess and musician to "try it out" anyhow. [Ethel P. Peyser, "The Rotarian," July 1926]
