To pose: To pretend, to be somebody you're not, to be part of a culture or genre just to fit in.

A person who attempts to blend into a specific social group.
Justin was such a poser-goth; sure, he comes to school in all black, but he doesn't even know who Edgar Allen Poe is.

a person - usually in middle or high school, who is insecure about him/herself and trys very hard not to be a "conformist" or a "prep," by doing things like: purchasing a skateboard or guitar, purchasing a great deal of clothing and accessories from hot topic, and listening to pop-punk bands such as simple plan, yellowcard, etc. usually, this supposedly "nonconformist" behavior just backfires on him/her, because now he/she is still conforming, just to a different group of people. so the moral of the story is to be yourself.

everybody according to someone. in reality a poser is someone who pretends to be someone they are not. only acting a certain way because they want to be accepted. the problem is someone is going to call you a poser no matter what. the term has lost all meaning really. i once heard a jackass call marilyn manson a poser. really? who is he trying to be if not simply himself? so in short everybody is a poser apparently.
bob: have you listened to the new gwar album?

jack: you like gwar? you're such a poser.

bob: you're a fucking idiot. why do we even hang out?
