What does “coludido” mean in Spanish?

“Estar coludido con alguien” means to be in cahoots with them — secretly working together to deceive or harm someone else. It comes from “coludir,” to act in collusion, and turns up constantly in Latin American news and courtroom talk: officials “coludidos” with cartels, companies “coludidas” to fix prices. The kernel is “colusión” (collusion), so once you know “coludido” you also recognise that headline noun.

Here the line is “sabré que estás coludido con los criminales” — I’ll know you’re in league with the criminals. It is formal and accusatory, far stronger than a neutral “trabajar juntos.” Note the false-friend trap: it has nothing to do with “colisión” (a crash/collision), despite the look-alike. For everyday speech you’d more likely hear “estar metido con” or “ser cómplice de.”
