An educated term for one whose daily life includes Communist rants on Reddit, unshaven armpits, and $8.00 coffees at Starbucks. It derives from the Latin, "Freeus Spiritus,' translated roughly as "Attends private liberal college with daddy's capitalistically earned money."
A euphemism for someone who deviates from his/her society's norms by not holding employment, not bathing, acting promiscuously, etc.
Josh dropped out of school and spends most of his time in his parents' basement smoking pot and working on his poetry, he's such a free spirit!! I'm going to have sex with him because he's such a free spirit!
One who does what he or she wants with little regard for anyone or anything: their self, family, job, etc. One who requires someone else to do it and will, while the free spirit bitches about the result.
