No single film or show is credited for this clip, which spread as a generic reaction sound on meme pages and soundboards. Its appeal comes from combining two reliable triggers, contagious laughter and a sudden scream, in one long take that builds without a break. That length lets editors trim it to a short laugh or stretch it for a full meltdown. It stays popular alongside other exaggerated vocal memes like the scream meme because it needs no context to understand.
