Signification
To behave in a wild, irrational, or foolish manner, often intentionally.
Contexte culturel
In Brazil, 'dar uma de louco' is often associated with the 'Malandro' figure—a person who uses their wits to navigate social and economic challenges. It's seen as a survival skill. Portuguese speakers use 'fazer-se de parvo' or 'fazer-se de desentendido' more frequently in formal or semi-formal settings. 'Dar uma de louco' is recognized but feels distinctly Brazilian. In modern Brazilian offices, 'fingir demência' has largely replaced 'dar uma de louco' among Gen Z and Millennials, though the meaning remains identical. In Rio, the phrase can be used more aggressively to mean 'don't try to trick me.' It's often paired with 'tá me tirando?' (are you mocking me?).

Sensitivity Check
Be careful using this around people who might be sensitive to mental health topics. It's a very casual idiom.
