To be brief, a "dickhead" is a cross between a "scene kid" and a "hipster."
Often superficial and a poser, the dickhead can be characterized by a distinctive clothing style crossing retro or vintage elements with wild flashy add-ons that vary greatly.
To discuss behavior, lifestyle, and activities, a Dickhead is someone who acts very self-entitled and "off the radar," (ie, "that's so mainstream") yet is very concerned with their standing within the dickhead microcosm, (similar to "indi-cred")
With interests revolving around worldly liberal events such as politics, world hunger, poverty, and other protest-worthy topics, the dickhead feels very enlightened and worldly. In addition, foreign short films, local music, and obscure micro-media are key points of interest. Clubs, cub-music, and club-lifestyle are central to the identity of the dickhead, so long and the prerequisite levels of "not mainstream" and "worldly/concerned/informed" are met.
MIKE: "Fucking dickhead."
DANE: "Careful, don't want to rumple my bright yellow scarf, or it will clash with my oversized 7-UP belt buckle holding up my purple bell bottoms, with my thin wool low cut V-neck sweater."
- What a dickhead!
