Tuuli is a finnish name for girls. It's not very popular name because girls with this name usually come from South-Eastern Finland and their behavior is commonly weird and they can quite out of their heads most of the time.

The word can be used as an adjective (tuuli) and verb (tuuling) too.
That chick is quite tuuli! Don´t be such a tuuli! Don't you start tuuling on me!
