Sleepy Boy Technique

The Sleepy Boy Technique is a hypnosis move used to put the opponent to sleep, by using hand motions and weird voice sounds. Jackie Chun used it to put Goku to sleep, though Goku awoke when Bulma shouted "Dinner Time!!!!" before the countdown was complete.

During the Tournament of Power in Dragon Ball Super, Master Roshi used this technique on the transformed Ganos. However, the latter was able to prevent himself from falling asleep by shocking himself awake.
