This clip is catalogued as a sneeze from Smugalana, a VTuber whose short vocal reactions are shared as soundboard clips for fans and editors. Like many VTuber moments, it was likely clipped from a stream and passed around because it is brief, clean and instantly recognisable as a sneeze. Reaction sounds like this stay useful because they need no context: anyone can drop them into a meme, highlight or chat moment and viewers immediately understand the joke. Its short length also makes it easy to reuse without slowing a video down.
