there is a way of liking labels that may seem pretentious, for example wearing hollister or listening to Justin bieber because your friends do...or even having the right car, like a Mercedes or a Lexus. But at least there's something sincere, open and honest about the people who admit they wear or purchase or listen to be socially in sync.
People who listen to things only when they aren't mainstream are an even more base and dishonest form of pretentiousNess, because they lie to others and possibly themselves that their motive for doing so is social. Its disingenuous and it makes me want to punch people in the face.
Id rather be near a sincere and honest conformist or social climber than some fuckface who pretends they aren't one.
