There are really only two things that define a Hipster: What they hate and when they start hating it.
Hipsters love things when they are indie and not well known, because they get a thrill off of being part of a small, tight-knit group of like minded people (who get to pretend they are better than others because of obscure knowledge). However, when and if such things become popular or mainstream, they lose their inherent value to hipsters because now it's not "theirs". It's something they now have to share with everyone. Once this happens, their love turns to resentment and one of two things happens.
- They leave the scene and look for something else to be exclusive about.
OR
- They stay in the scene, proclaim they liked it before these new guys came in and keep pretending they are better for it.
Hipsters can be from any walk of life because EVERYTHING starts out indie. For example, the following are hipsters:
- People who only like the Final Fantasy games before 7.
- People who make a point of saying they knew a band when they were still working empty bar rooms.
- People who hate the fact that Call of Duty/Halo/Mario/whatever is the only game some people play.
- People who only drink imported or locally brewed alcohol (and only the actually imported stuff, not stuff made in the US/Canada under a foreign label).
- People who hate people who've only seen the movie of a book, not read the book.
- People who watch foreign movies and then complain about American remakes. (I'm guilty of this one)
- People who only watched subtitled anime.
- People who wear ANYTHING ironically.
- People who only read comics from companies other than DC, Marvel, or Darkhorse. Doubly so if they only like Black and White ones.
- People who carry a lunchbox for a series that went off the air over five years ago AND are over the age of 10. Double points if it's tin or another metal.
- ANYONE who thinks their fandom makes them special or better than other people.
I'm sure just about everyone meets at least one of these examples... however, what TRULY makes you a hipster is to the degree to which you hate. If these things just bother you, but don't drive you crazy, your not a real hipster. However, people who define themselves by these things are.
