How do you 'turn' hipster?
Isn't being a hipster a wee bit more than just having a 'nerdy' look? First and foremost, the term 'hipster' as it is currently used, in no way represents what it actually stands for, i.e. a person who has happened to acquire his own thoughts, own style, own interests in certain musical sub-genres in a manner that reflect his distinctive personality as a whole.
Hipsters, from my experience, don't just turn up out of nowhere. It's a group of people sharing common beliefs, interests, hobbies, thoughts and a way of expressing themselves, having behaved thus through over course of a longer period. Hipsters, in sociological terms, would probably fall under a sub-culture that does not share the norms and beliefs of the majority - it's a sort of a counter-culture, to be more precise.
The spread of social media has, nonetheless, made certain elements of such counter-cultures trendy and they have, to an extent, lost their meaning as the more mainstream things become the more people acquire certain traits for either finding them appealing (without understanding their origins) and / or because they are growing popular amongst either their peers, or, en masse. However, despite acquiring some traits, they fail to acquire others and thus become nothing more than imitations of each other without the certain je ne sais quoi.
So no, Neymar and Dani are not a hipsters and will never turn into hipsters, as they are simply acquiring certain bits and pieces of popular trends.
