SpongeBob's laugh comes from SpongeBob SquarePants, the animated television series that debuted in 1999. The character's voice, including this famous laugh, became one of the show's most recognizable audio cues. Over time, it spread far beyond the series through meme compilations, reaction videos and short-form edits, where creators use it to signal goofy chaos or playful ridicule. It remains popular because even a brief clip is immediately identifiable and adds a strong cartoon tone without needing any extra setup.
