How did you find out you were a hipster?

The same thing just happened to me. My friend called me a hipster and I laughed at it. Then I googled "what is a hipster" and went to Urban Dictionary. The first definition is clearly pro-hipster, and it described me almost perfectly, except for the age part (I'm 14). I've decided I'm gonna embrace it. Whether we like it or not, labels are real.
