Place it as the reply beat after the clip that sets up the complaint, then follow it with the damn meme sound for the other person's stunned reaction, or swap that follow-up for the eww brother eww sound when the complaint is gross.
Sobre este som
This clip is a spoken French voice line saying 'je m'en fous aussi' — I don't care either — stretched over about ten seconds in a flat, dismissive delivery. It feels funny and unbothered rather than angry, turning a shrug into a comeback that lands when someone expects you to care and you clearly do not.
