This is a very short Portuguese voice clip, under a second long, delivering the phrase 'Não me importa', meaning 'I don't care', in a single quick line. It feels blunt and funny because the dismissal lands instantly, with no explanation or softening. It works as a confident shrug in words, perfect for cutting off a conversation you have no interest in continuing.
