The phrase itself is a common, blunt way to ask about an unfamiliar person, and as a short audio clip it has found a second life online as a reaction sound. Creators lift it for moments of confusion, disbelief or comic confrontation, especially when a new character, stranger or unexpected face appears without warning. Because the delivery is so direct and the clip is only about a second long, it works as a quick punchline in short-form videos, meme edits and streams, where viewers instantly recognise the feeling even without any context.
关于此声音
A short, incredulous voice clip asking who the hell is this, used as a reaction sound effect for unexpected appearances and confused introductions in memes.
This is a brief, sharp voice clip lasting just over a second, delivered with blunt surprise and a rising, almost accusatory tone. The speaker sounds genuinely thrown off, as if someone completely unexpected has just walked into the room or appeared on screen. There is no music or background noise, just the direct question, which makes it land instantly and feel confrontational in a funny way. Used in an edit, it freezes the moment, tells the viewer to share the confusion, and turns an ordinary reveal into a punchline without needing any explanation.
