Someone who liek listens to music about getting high and they never do, listen to christian bands and still do bad things, or listen to punk bands when they really arent into the music. You get the point.
People who try to be something they are not, but it is opparent that they are just "posing". Posers ussually drive rice cars, and listen too pop-punk music. People who listen to metal or rock are not posers.
what you are if you have a friend that decided they wood be an individualist and become punk like the 5 billion other punks in the world before you. you are the poser until one of your friends then decides they will be punk too and then you can call them a poser...
