Place it as the reaction beat after a failed move, following Roblox Oof for the mistake and letting this clip answer it, then cut to Nope if the player doubles down on the same obvious error.
关于此声音
This short Roblox clip is a single spoken 'duh', lasting about two seconds, delivered in a flat, dismissive tone. It lands as a quick, sarcastic nudge, the kind of sound that makes an obvious statement feel even more obvious and a little awkward. It works best as a brief reaction, cutting in exactly when someone has just missed the point.
