Place it as the final reply in a short exchange, after a complaint clip and before a reaction, so the dismissal lands as the punchline. Pair it with Bruh for a follow-up reply, or follow it with Emotional Damage when the other person overreacts, keeping the sequence short and focused on the exchange.
About this sound
This is a short Portuguese voice clip, lasting about six seconds, in which a speaker delivers the line 'E quem disse que isso é problema meu' with a flat, unbothered tone. It feels dismissive and cheeky, turning someone else's complaint into a joke, and it works best as a deadpan brush-off when a listener is refusing to take responsibility for a problem that is not theirs.
