This is a short Portuguese spoken reaction lasting about two and a half seconds, built around a single emphatic line delivered in a loud, confrontational voice. It lands as a blunt, mocking callout, the kind of dismissive jab that makes a bad suggestion sound instantly ridiculous. The tone is playful rather than angry, turning a wrong idea into a joke the whole group can laugh at together.
