Criança descobre que antigamente quase não tinha igreja

What does “que doido” mean in Portuguese?

Que doido is the everyday Brazilian way to say “how wild” or “that’s crazy” when something surprises you. Doido means crazy or out of your mind, so que doido is pure amazement — the spoken equivalent of an English “no way!” or “that’s nuts” — and you’ll hear it dropped into conversation constantly. It’s a reaction you reach for the instant a fact catches you off guard.

It belongs to a whole family of one-line reactions: que louco and que loucura (“how crazy”), que doideira, all interchangeable with que doido. The kid here lets it slip on hearing that the church building used to be an ice-cream shop and a two-storey cinema — and that, long ago, there were barely any churches at all. That casual Que doido is exactly how a Brazilian processes a surprising fact mid-conversation. The root doido (from older doudo, origin uncertain) also lives in doidamente (“madly”) and endoidar (“to drive someone crazy”).
