There is no widely documented film, game, or television origin for this particular Lok jumpscare clip, and it circulates mainly as a short user-shared soundboard effect rather than a famous movie sting. That is typical for modern jumpscare audio, which spreads through horror edits, gaming videos, and prank compilations where creators need a ready-made shock they can drop in instantly. Its short length and abrupt impact keep it useful long after its first uploads, because a good scare does not depend on knowing the source, only on timing and surprise.
