Wikipedia: Bunny hop (dance)
The bunny hop is a novelty dance that was created at Balboa High School in San Francisco in 1952. It is a social mixer dance, sometimes also referred to as a “party” or “dance party” dance.
 
History
The dance has been generally done to Ray Anthony’s big band recording of the song with this name. It was a vocal hit in 1952, and instrumentally re-recorded c. 1958. The song has been re-recorded by others, including musical updates of the style, for example, a Salsa version. Duke Ellington recorded “Bunny Hop Mambo” in 1954. Other popular music of the era is also used, such as “The Glow-Worm.”
