amurrarse

Latin American colloquial, especially in the Andean region (Peru, Bolivia, Ecuador, Chile): to sulk, pout, or go quiet and moody — se amurró porque no lo dejaron ir. It describes a specific silent, sullen withdrawal rather than open anger.

• El niño se amurró porque no le compraron el juguete. — The boy sulked because they didn't buy him the toy.
• No te amurres, ya te explico lo que pasó. — Don't sulk, I'll explain what happened.
• Se amurra cada vez que pierde en el juego. — He pouts every time he loses at the game.

Using amurrarse outside its Latin American colloquial contexts and expecting it to be understood everywhere — in Spain, enfurruñarse or ponerse de morros are the equivalent everyday choices.

Often confused with enfurruñarse.
