A hipster is somebody who does what they want and explores what they find interesting

This is the opposite of hipsterism. Hipsterism is about trend following and that is what people find humorous about it, because the people associated with it generally express a disdain for trend following.

It's no different than what happened in high school with the cookie cutter "non-conformists" (goths and punks were examples when I was in high school). The difference is that hipsters often carry that on long after high school.

That's the cliche, but that's not how it works. I'm in the middle of so-called hipster culture. There are no trends and there isn't really a disregard for trend following. There's more an apathy toward the entire concept of trends. There's also not much self-obsession, either: My friends who wear obnoxiously oversized glasses usually bought them with other friends and wear them because they think it's funny. It's not a nonconforming thing and it's not a trend. If anything it's more of an impulse.
