In Spanish slang, 'cocodrilo' is often used to describe a person who cries or complains a lot, similar to the way a crocodile sheds 'crocodile tears'. It can also be used to describe someone who is deceptive or not sincere.
Examples
- Spanish: No llores como un cocodrilo, sabemos que no te importa realmente.
- English: Don't cry like a crocodile, we know you don't really care.
