diñarla

A vulgar, colloquial fixed expression meaning to die, croak, kick the bucket — from caló diñar ("to give"), diñarla literally means "to give up [life]." Common in informal spoken Spanish, especially in Spain.

• Casi la diño cuando me enteré de la noticia. — I nearly croaked when I heard the news.
• El protagonista de la película la diña al final. — The movie's main character kicks the bucket at the end.
• Como sigas fumando así, vas a acabar diñándola. — If you keep smoking like that, you're going to end up dead.

Using diñarla in formal or polite contexts — it's crude slang for dying, on par with English 'kick the bucket' or 'croak'; morir or fallecer is what you'd use with people you don't know well.

Often confused with morir.
