This catchphrase is associated with Sketch, a streamer and online creator whose “What’s up brother” greeting became widely repeated in short-form videos and meme edits. The clip spread across TikTok and repost pages as people used it for comedic entrances, ironic greetings, and recognizable creator references. Its staying power comes from how short and flexible it is: the line is instantly identifiable, easy to place over a cut, and funny even out of context.
