A pretentious and self-absorbed hypocrite who has abandoned their sense of identity to fit an exaggerated trend or theme. In order to cope with their confusing psychological denial and low self esteem, these sad individuals project their lack of definition and depth at the world thereby inflating their own perceptions of uniqueness. They can be found simultaneously condemning the cultural "mainstream" on superficial topics such as style or fashion, while engaging in hyperbolic applications of those same superficial aspects.
While some of these individuals may genuinely struggle to become more cultured, most do not have a genuine interest (or aptitude) and are simply trying to fit into a crowd that wants to reject fitting in to the "mainstream". Conversely, a socially well adjusted individual who truly appreciates and participates in art, for example, may have no inclinations towards the hipster subculture. There is somewhat of a one-way, pretend inclusion that the hipster conceives of for him or herself that is a form of mild delusion.
Hipsters present a curious irony by considering themselves superior, more cultured and more individualistic, while rejecting the actual depth, perspective and variation in people around them that is at the core of individuality.
Guy 1 : Why was that guy rude for no reason?
Guy 2 : He's a hipster.
Guy 1 : Ahh - I guess that's why hes dressed to solicit attention and we're not at a costume party.
Guy 2 : Hipsters are douchebags.
Guy 1 : Yeah, I've heard that before.
