What is a poser?? Someone who pretends to like the same thing as you, try to be like a group of people???. then most people are posers, cause everyone wants to be excepted. And why is the reason that you hate them? Do they effect you in anyway or anyone for that matter none the less.. You most likely hate them because you feel like they're stealing your identity which is your fake identity. Thats not healthy. Sry, for my critique, but i hate the word "poser". We are all posers!
