Unlike a famous movie quote or viral catchphrase, the tummy grumble is a generic sound effect that has circulated on soundboards and editing libraries for years as a quick shorthand for hunger. Creators reuse it because it needs no explanation: a stomach rumble is understood across languages and ages. It appears in comedy sketches, animations, gaming streams, and short-form videos whenever a joke depends on craving food, dieting, or waiting too long between meals, which keeps it useful long after any single trend fades.
