alternative lifestyle haircut (n) – A haircut or style that indicates its owner leads a life contrary to that of the conservative or heterosexual world. Also known as “the significant lesbian haircut,” the acquiring of an alternative lifestyle haircut is often seen as a rite of passage into lesbian adulthood, even if it is not maintained after the initial cut. Like a bat mitzvah, but on your head. Examples include: the mohawk, the fauxhawk, the mullet, the sidesweep, and the Tegan and Sara.
The term was coined by Autostraddle.com and has since become a common collloquialism.
1.) Jess just came out and, after going to her first Tegan and Sara concert, got an alternative lifestyle haircut similar to Tegan's.
2.) Once Leah added an alternative lifestyle haircut to her outfit composed of American Apparel and a skinny tie, she became infinitely more attractive.
