The phrase is Russian slang aimed at immature kids behaving foolishly, and online it survives mainly as a soundboard button rather than a clip tied to a known show or streamer. Its very short length helped it spread in gaming and meme communities, where editors reuse the same distorted shout as a reusable reaction. Posted with tags like meme and lol, it is shared less for context and more for timing, dropped into unrelated videos whenever a brief, rude label for chaotic behaviour is funnier than explaining the joke.
