Hipster means different things to different people. For many it’s a cheap insult; an all-encompassing term for the shallow, the insincere trend-followers. Whatever comprises the actual subculture the perception tends to be entirely negative.
Hipsters are a subculture of men and women typically in their 20's and 30's that value independent thinking, counter-culture, progressive politics, an appreciation of art and indie-rock, creativity, intelligence, and witty banter.
Hipsters reject the culturally-ignorant attitudes of mainstream consumers, and are often be seen wearing vintage and thrift store inspired fashions, tight-fitting jeans, old-school sneakers, and sometimes thick rimmed glasses.
