About this sound
This is an eight-second spoken clip of the Portuguese line 'Detroit me deixa em paz,' delivered as a direct plea to be left alone. It carries a fed-up, dismissive feeling, the kind of exasperated reaction that lands when someone has pushed too far and the speaker wants the conversation to stop right there.
