Place this clip as the immediate reply after the unbelievable claim in your edit, then follow it with the emotional damage meme sound if the callout needs a bigger payoff, or end on the bruh sound effect for a flatter, drier finish.
Sobre este sonido
This is a short Hindi voice clip of the line 'Acha ji, aisa hai kya,' spoken in a curious, teasing way over about five seconds. In English it works like 'Oh really, is that so?' It gives a listener a mix of amusement and doubt, like a playful callout that is not quite buying the story being told.
