Put this clip directly after the bait line in your edit, preceded by oh my god wow for the shocked reaction, then close the sequence with nelson's ha-ha so the mockery lands last and the argument fizzles out completely.
Sobre este sonido
This is a 6.5-second spoken clip in Portuguese where a voice says 'Não me importo,' which translates to 'I don't mind.' The delivery feels flat and dismissive, giving listeners that shrugging, completely unbothered mood you use when something is meant to bother you but lands with zero effect at all.
