This technique is used to trap their opponents by causing them to lose control of their bodies and dance uncontrollably, thus making them defenseless against attacks.
The Para Brothers use this on Beehay against Goku, Trunks, and Pan and are able to knock them out, giving them the necessary time to retain the Black Star Dragon Ball which Goku, Trunks, and Pan had left in their spaceship. However, the Moumas scared the brothers and Goku, Trunks and Pan, regained control of their bodies and knocked them out.
