In some regions, 'cuca' is a colloquial term for 'head' or 'mind'. In other contexts, it can also be slang for a woman's private parts. Use with caution as it can be considered vulgar.
Examples
- Spanish: 1) Tienes que usar la cuca para resolver este problema. 2) Esa mujer tiene una cuca muy atractiva.
- English: 1) You have to use your head to solve this problem. 2) That woman has a very attractive private part.
