Place it as the closing beat after the visual gag, then follow it with We Do Not Care Sound for a dismissive follow-up, or open with Hell Naw Dog Sound before the reveal so the blunt line works as the closing comment.
About this sound
This is a short, roughly two-second spoken line in Portuguese saying “it’s funny because he’s fat,” delivered quickly and dryly, without any build-up or extra voices. It feels blunt and awkward, turning an ordinary visual gag into a deliberately uncomfortable laugh, as if someone stated the obvious at exactly the wrong moment.
