punker
Someone who listens to punk music and has adopted the style, aesthetic, and ethos associated with it. I care very deeply about being a true punker, but it means I'm rarely given a fair chance at job interviews for companies that aren't open to more alternative looks. I was a bit of a punker back in college, but my musical tastes mellowed out somewhat after I graduated.
