Although no single original video is widely credited for this clip, the horse laugh has become a staple of meme soundboards and short-form comedy, where animal sounds are used to exaggerate human reactions. It spread through reaction videos, gaming highlights and TikTok-style edits, where a loud, unexpected animal laugh can turn a small mistake into a joke. Like the baby laughing meme and the cat laugh meme, it works because the laugh feels out of place, making the moment funnier without needing any dialogue or explanation.
