The sound comes from Sr Pelo, a Mexican animator and YouTuber whose exaggerated cartoon style and distinctive laugh have become a recognisable part of his Top 10 videos. Clips of that laugh were shared as a standalone reaction sound, and creators began dropping it into edits, rankings and commentary videos whenever a moment turned absurd. It spread through meme edits and short-form video rather than as a formal release, which is why it works best as a quick punchline. Like the baby laughing meme, it relies on an instantly recognisable laugh to signal that something is funny.
