The origin of this stretched yell is not clearly documented, so its life online comes from soundboard sharing and short video edits rather than a known film or show. Clips like this and the goofy yell spread because a single exaggerated voice line can stand in for panic, pain or excitement without any context. Creators reuse it as a quick prank and reaction sound, layering it over gameplay, fails and memes where a normal scream would be too short or too serious to be funny.

A short, drawn-out hyaaaa yell sound effect with a breathy, strained voice, used for prank moments, over-the-top reactions and funny scream edits.
This clip is a stretched out vocal yell that starts with a breathy hhh sound and slides into a long, wobbly hyaaaa. The voice sounds strained and exaggerated, holding the note far longer than a normal shout would last. There is no music or background noise, just the raw yell getting louder and more dramatic as it goes. That overdone delivery is what makes it funny rather than scary. Viewers hear it as instant panic, excitement or mock pain, and the length gives editors plenty of time to build a joke around the reaction.
