1. Someone who does something they dont want/like to do to please people whether it be punks, goths or even preps. yes, preps.
2. Someone who doesn't act like themselves.
1. Why is that prep trying to act like a hardcore person? What a poser ~or~ why is that hardcore person trying to be preppy? What a poser.
2. You can only tell if someone is a poser if you ask them if they like being hardcore or preppy or whatever. If they dont and they say they're only like that to please others then they are a poser. If you define a poser by what they where then all goths are posers and all preps are freaks.
3. I am sorry if i have offended anyone.
