Put it near the end of a short reaction edit, after the confusion has built up, then follow it with an Anime Wow for the payoff and a Vine Boom to close the beat. Keep it as the joke's turning point rather than the opener, so the paired sounds land in that order.
关于此声音
This is a short, roughly nine-second vocal clip built around a playful, baby-like gugugaga babble, delivered in a loose, sing-song patter that sounds like improvised nonsense. It feels silly and lighthearted, the kind of goofy noise that makes a chat pause and smile rather than taking anything seriously. It works as a quick burst of absurd humour with no message behind it.
