The name comes from gachiHYPER, a well known emote in Twitch chat culture connected to the wider gachi meme scene that grew around remixed wrestling videos and Billy Herrington clips. In chat the emote signals intense, ironic excitement, and soundboard versions turn that same reaction into a short audio button. The OK wording keeps it flexible, so the clip moved easily from stream chat jokes into meme videos and group chats. It remains popular because two seconds is enough to mark approval while still sounding completely over the top.
