Place it at the end of a reaction sequence, after the obvious statement has played out, so it closes the moment instead of opening it. Follow it with a short Bruh for a second reaction beat, or pair it before Fahhh when you want the response to build across two similar clips.
关于此声音
This is a short, drawn-out vocal clip lasting about three seconds, built around a slow, sarcastic-sounding 'duhh fahh' delivery that stretches the syllables for comic effect. It feels dismissive and knowing, like a deadpan response to something painfully obvious, and lands best as a quick reaction rather than a punchline on its own.
