Over dit geluid
This clip is a single drawn-out vocal ooh, stretched over about 1.3 seconds as one voice holds the sound without words. It gives a listener a sense of amazed disbelief and playful shock, like a reaction that keeps growing instead of stopping short, which makes the moment feel bigger and funnier than a quick gasp would.
