Sobre este sonido
This is a 5.7-second voice clip of a man shouting in Portuguese to speak Portuguese, calling the other person an alien. The delivery is blunt and exasperated, which makes it feel funny and confrontational at the same time, like a fed-up reply to nonsense that sounds completely incomprehensible.
