MLG montage parodies grew out of online gaming culture in the mid-2010s, when editors exaggerated competitive gameplay with loud sound effects, distorted audio and ironic reaction clips. The ooooh became shorthand for mock amazement, a way to hype up a play while making fun of hype itself. As montage edits spread across YouTube and later short-form video, the sound travelled with them, detached from any single video and reused as a ready-made reaction. It survives because that sarcastic, over-the-top tone still fits fast gaming edits and meme compilations.
