Place it immediately after the loud outburst in your edit, not during background chatter. Pair an exaggerated scream using the auughhh meme sound before it, then follow with the we do not care sound for a second dismissive beat when the person keeps talking.

This is a 1.8-second voice clip of the Brazilian Portuguese line “fala baixo nengue” spoken in a playful, scolding tone, like telling someone to lower their voice. It feels funny and dismissive rather than angry, because the correction is blunt, quick and exaggerated, turning a loud moment into a joke at the speaker's expense.
