The Akiyamaaki OMG clip circulates as a user-uploaded reaction sound, the kind of half-second exclamation that thrives on short-form video and livestream chats. Nobody needs to know who first recorded it for it to work: the joke is the timing, not the backstory. Editors drop it over fails, reveals and jump scares because a genuine-sounding gasp sells surprise better than any caption. Its staying power comes from that simplicity, a universal reflex compressed into under a second, ready to fire the instant something unbelievable happens on screen.
