The Urban Dictionary (www.urbandictionary.com) defines a flipster like this:
Flipster: Someone who dresses however they want. They don't have a specific style. They make fun of other groups of people especially Hipsters and Scene kids. Unlike Hipsters, Flipsters don't deny being a Flipster. They could care less what others do. Flipsters are Too Hip To Flip.
Interesting...because that may be a perfect description for "over 50 me." After a lifetime of conforming on a multitude of levels, I realize that I've lost the feeling that what someone else thinks may be more important that what I think about my life. The rationale is pretty basic stuff: I have to walk around in my skin. I have to live this life. I know who I am and who I am not. Clarity is awesome.
I may not be hip, but I've definitely flipped.
