An insufferable, pseudo-intellectual twerp who defines his identity mainly through allusions to, and alleged knowledge of, obscure popular culture, often of the ephemeral variety. This urban poser advertises this identity via vintage clothing, thick-rimmed glasses, and ironically or iconically decalled t-shirts, oblivious to the concept that his conformity to a predefined template for appearance undermines and contradicts his attempt to be an independent thinker. He exibits a strong narcissism in the form of his constant hunt for attention and self affirmation via online social networks and communications technologies, through which he believes he is channeling relevant, interesting, and enlightening information, but which he usually employs to boost his hipster cred by making obscure references, parroting Internet memes, and generally proclaiming the superiority of his tastes. In quiet desperation, however, the hipster is racked with anxiety, as he is constantly driven by a desire to be "in on the joke" - the concept that other hipsters may be enjoying something of which he is cluelessly unaware, that he may not understand the disposable 90's movie reference which sent his peers into a titter, is anathema to this self-satisfied but inherently insecure social animal.
Mark cursed softly as the hipster in the aisle paused next to him to stow his Apple-logo messenger bag in the overhead bin. The Banana Splits t-shirt at eye-level and the thick, horn-rimmed glasses looking down at him told him that he was going to be in for a long flight filled with tedious conversations about the power of social media to help the unemployed take the country back from evil corporations.
