Someone who doesn't care about religion or any type of belief based on the creation of the universe. These people believe that searching for answers that so far haven't been proven is wasting valuable time that could be spent living life. These people AREN'T atheists, they just don't believe in anything about the creation of the universe.
Christian: "I asked that guy if he was a Christian... He just said he was a free-spirit and that he didn't believe in that stuff."
Atheist: "So he's an atheist?"
Christian: "No... He just said that he doesn't care enough to believe in ANYTHING. Not even the things you guys believe in."
Atheist: "That's new..."
A Free Spirit is a person, animal, or object that is "free" from all wordly concerns and can act of his own choosing. Free Spirits are relaxed, cultivated, and free.
