The clip is labelled as the jumpscare sound from Five Nights at Jlibby Robin's Remake, a fan-made project that borrows the sudden-attack structure made familiar by Five Nights at Freddy's. Rather than a long musical cue, it uses a single explosive scare moment, which is why short-form editors and horror-game fans keep it in rotation for reaction videos, edits and soundboard pranks. Its brevity also helps it travel: the whole scare fits into a single cut, so it can be reused without trimming or timing work.
