Listed online as Risa Incontenible, Spanish for uncontrollable laughter, this clip circulates on soundboards and meme pages as a generic reaction laugh rather than a line from a known film or show. Short laughing clips like the baby laughing meme and the cat laugh meme follow the same pattern, getting reposted for edits, streams and chat replies. Its length makes it useful when a quick giggle is too short, letting editors stretch the joke while the laughter builds, peaks and finally runs out of steam.
