This clip circulates online mainly as a general reaction sound rather than a clearly documented quote with a widely agreed source. Its popularity comes from how quickly it communicates approval, excitement and comic triumph in very little time. Short celebratory shouts like this spread well across meme pages, group chats and quick-cut videos because they fit almost any payoff moment. It is still used in edits for the same reason as sounds like bruh or YAAAAAAAAY: the emotion is immediate and easy to understand.
