They then started making up arm movements for the dance, which prompted the birth of the Swim, the Monkey, the Dog, the Watusi, the Mashed Potato, and the Jerk.
The movie Sweet Charity (1969) contains a number called "The Rich Man's Frug", a wildly energetic dance number comprising three "movements" ("The Aloof", "The Heavyweight" and "The Big Finish") that showcases director Bob Fosse's distinctive choreography style, particularly his creative use of unusual poses, gestures, and arm movements.
The evolution of Frug also signified maturation of theatricality in Fosse's choreography, departing regimentation towards visual dissonance, where every dancer could perform their own moves.

"Frug" was also included in the soundtrack to the Christina Ricci film Desert Blue, which led to the band's heightened popularity and eventual signing to a record label.
