Goku, the hero of Dragon Ball, is famous throughout the long-running anime for an appetite that matches his fighting power, often eating enormous meals after training or battle. That running joke made his chewing a natural clip for fans to isolate and share on anime soundboards and social video, where the sound works even without seeing the scene. It spread because the gag is simple and universal: hunger, speed and total lack of restraint. Creators still reach for it whenever they want an instant anime shorthand for someone eating far too much, far too fast.
