Place it as the final beat after a complaint or excuse has played out, so it closes the exchange instead of starting one. Pair it first with a long venting clip, then let this dismissal answer it, and follow with a short laugh clip.
Über diesen Sound
This is a short spoken clip in Brazilian Portuguese, lasting just over a second, in which a voice tells someone to keep their problems because the speaker does not care about them. The delivery is blunt and unbothered, with a shrug-like finality that makes the dismissal feel funny rather than angry. It lands as a quick, confident brush-off for an unwanted complaint.
