Actually, I think you have this reversed. It should be 'free-spirited'. The other way makes no sense in English. This word, 'free-spirited', is an adjective used to describe a person as being liberated, a bit more on the casual side & unrestricted. It has been used in recent years to refer to hippie-type individuals or those of a bohemian mentality. It's someone who cannot be tied down or made to conform. They are free thinkers and may be somewhat 'gypsy-like'. :)
