The clip was taken from a Twitch stream by FamousHorse and circulated as a standalone reaction sound. Short streamer outbursts like this spread because they are easy to lift from live broadcasts and reuse out of context in other streams, compilations and meme edits. Its appeal is the universal confusion in the question, which fits almost any strange statement or unexpected event online. It remains popular as a quick verbal reaction rather than a longer rant, letting creators borrow a streamer's disbelief without needing the original stream for context.
