The clip circulates online under the name K9Kuro, a VTuber and streamer known for chaotic, joke heavy streams, with bussy taken from wider internet slang that has been used in memes for years. Short isolated voice lines like this spread through soundboards, Discord servers and short form edits because they need no context to work as a joke. Rather than coming from a scripted scene, its popularity comes from repetition, with fans clipping streamer moments and reposting them until the single word becomes a recognizable in joke.
