Ok, so most of the definitions of this word circulating are wrong. Yes I said it. The word hipster stems from the word hip. It is safe to say that 'hip' can be defined as 'what is cool right now'. A hipster can be defined as a person that adopts fashion, music taste, behaviours, blablah of what is considered 'cool right now'. It's just logic. Just Google "define: hipster" and you shall see that I am not talking utter bullshit. So anyone saying a hipster is trying to be 'independent' and striving for 'individuality' and is somewhat 'unique' or what ever crap I hear, you are wrong.
A hipster is a person that involves themselves with a popular scene. So now we have to understand that a 'popular scene' is subjective to the area you live in. So where I come from (england) a hipsters traits are as follows: chino jeans, listen to house music such as 'Swedish House Mafia' and 'Skrillex', vest tops, fake tan (men and women), identical to all of their friends, watch Jersey Shore, Georgie Shore, TOWIE and other crap like that. Paradoxically, the most defining trait of a 'hipster' are those that throw around the word 'hipster' its self because using the word 'hipster' is actually what is popular at the moment. So if you like to use the word hipster, you my friend are a HIPSTER. Yes, it is obvious I am going to get a lot of thumbs down on this definition because most people are just ignorant. However, I have matured to learn that people are dumb and don't listen to reason or logic.
WRONG USE - "Yo, that guy in the flannel shirt with a fleet foxes band shirt underneath and the old film camera round his neck is a massive hipster."
RIGHT USE - "That young fellow there that looks like he dropped out of school and had to do his GCSEs at college and now in a dead end job; slaving away to some fat rich person behind a desk. He seems to spend the majority of his life projecting his own problems on to other people that are above him in society, sleeping around with as many women as possible in order to raise his rank in his cave man attitude driven friendship group. His vest, chinos, comb over and fake tan make him look very hipster!"
