Place it at the very end of a reaction edit as the closing reply, after the setup clip. Follow a failed attempt with the awkward crickets sound button first, then end on this clip so the sequence reads as an awkward beat, then dismissal.
このサウンドについて
This is a 25-second voice clip built around Wanessa Wolf delivering the Portuguese swear 'fodasi' as a blunt sign-off. The delivery reads as fed up and dismissive rather than angry, which gives listeners that funny, eye-roll feeling of someone completely done with a situation and choosing not to care anymore about it at all.
