How to Say “You’re Crazy” in Spanish

estás loco
/estas loko/from spelling rules
The English phrase "you're crazy" is translated into Spanish as estás loco.
estás loco is an expression used to tell someone that their ideas or actions are irrational or foolish.

Which one should you use?

You can use ¡Estás loco/loca de remate! to emphasize that someone is completely or extremely crazy. For a more colloquial tone, you can use ¡Estás chiflado/chiflada! to mean someone is crazy or mad.

Is it said differently in some regions?

In Spain, you might hear Estás como una cabra (literally: you're crazy like a goat) or Estás pirado/a (meaning: you're nuts). In Mexico, the phrase Estás mal de la cabeza is used to mean you're messed up in the head.

How does it change in a sentence?

The phrase uses the verb estar (estás), which implies a temporary state of being crazy rather than a permanent mental condition. Use the feminine form estás loca if you are speaking to a woman. To address a group of people or to say "they are crazy", use the plural form están locos.

Did you know?

  • In some contexts, ¡estás loco! is used as a high compliment to describe someone with an incredibly bold or daring spirit.
  • The word chiflado comes from the verb chiflar, which means to whistle, suggesting a 'whistling' or airy mind.
