Über diesen Sound
This nine-second Portuguese clip has a male voice frantically shouting eu tenho aids, massa cinzenta and HIV, then stretching tesão into a long, distorted scream. The delivery feels raw, exaggerated and deliberately offensive, meant to startle listeners first and then make them laugh at how extreme and absurd the escalation becomes.
