Or dope. Or whatever the lit people are saying these days. INTRODUCING IT'S NOT BLACK, IT'S OBSIDIAN. ...our all new obsidian on obsidian Circle Gs. By definition, obsidian is the hard, dark, glass-like volcanic rock formed by the rapid solidification of lava without crystallization. It's the perfect name for our hipster-y-est style, since by definition a hipster is the hard, dark, glass-like person formed by the rapid solidification of personality without self-actualization.
