K9Kuro is a VTuber and streamer whose short clips are frequently clipped and reused by fans as reaction sounds. This lizard noise became one of those shareable moments, with viewers isolating the vocal chirp from its original stream context. The no BGM edit removes background music so the noise can be dropped cleanly into other videos, streams and soundboards. It stays popular because it is instantly recognisable, extremely short, and works as a punchline without needing any setup or explanation from the original broadcast.
