The exact origin of this particular 'ohhh' reaction clip is unclear, but sounds like this became common across meme pages, gaming montages and short-form reaction edits. Its popularity comes from how quickly it signals collective shock, mockery or suspense without needing dialogue. Editors often use it in the same role as exaggerated reaction staples such as the Inception Button or a FNAF Jumpscare Scream, especially when a moment needs extra drama or a playful public roast.
