The phrase comes from everyday Brazilian Portuguese slang, where 'puto' is a vulgar way to say someone is very angry or fed up. Online, the clip circulates mainly as a reaction audio on soundboards, in WhatsApp groups and in short meme videos. Its appeal is the direct call-out: instead of describing anger, it asks the room who is mad, turning irritation into a joke. That makes it reusable for sports losses, gaming fails, work complaints and friendly arguments where the anger is not serious.
