I want to be an edgy hipster
That's weirdly specific. Why do you want to be an edgy hipster?
I want to hang out with my friend and his edgy hipster buddy
Pretending to be someone you're not for long enough will cause you to lose the person you really are. You should find friends with the same likes as you and learn to accept yourself so that others will do the same.
What will you do if I don't care what you say and I go to hang out with my lyfe's edgy hipster buddy?
You can do what you want, I'm just trying to say that you shouldn't lose sight of your true self if you keep trying to imitate other people. How about getting into the culture legitimately, and not just posing? You might like the lifestyle for real.
