The clip comes from a karaoke stream by VTuber Caren, whose channel name is written as 角蓮Caren, and it captures a brief, light-hearted noise she made during the broadcast. Shared as a short soundboard clip, it has circulated mainly among viewers who enjoy her singing streams and playful vocal moments rather than as a wide viral meme. Its appeal is simple: the sound is instantly recognisable as boiling water, yet clearly performed for fun, so creators reuse it as a quick, low-effort reaction that adds personality to edits without needing context from the original stream.
