This sound is tied to online reaction edits featuring Goku, the central hero of the Dragon Ball franchise. Rather than relying on a long scene, creators use the brief audio as shorthand for shock, confusion, or an unbelievable reveal. It has circulated through anime memes, short-form videos, gaming edits, and image-based reaction posts. Its continued use comes from Goku’s instantly recognizable expressions and the flexibility of the reaction format. Related edits also pair the character with music-driven jokes such as goku drip.
