A poser is essentially everybody in High School who actually pays attention to fashion/studies how to conform to a specific group. Generally, someone who is socially awkward and/or physically unattractive gets called a poser when said individual tries to fit into a certain group, usually comprised of people who have been studying how to conform for a longer period of time. However, since all High School cliques are based on extreme superficiality, the word poser could apply to everyone in such a group. The idea that anyone is, in fact, a "real" punk/goth/hipster, etc, usually stems from how much dedication they have to putting together their personality. It's usually born from a psychological condition that has been impeded into their brain through corporate propaganda; more or less, the idea that you need to consume/conform on some level to have an identity at all.
When you are using external sources and symbols to define your personality, you are not actually being "real" in any sense, and that's especially true if the symbols have been given their meaning independently of yourself or peers. Peer pressure and conformity, of course, are normal adolescent behaviors, although teenagers take this to an extreme in consumerist societies (and corporations exploit this condition in teenagers as well, hence how important the word "poser" seems to be here on urbandictionary).
It should be noted, however, that some hipsters take this thought process deep into their twenties, and never fully mature past the point of making an identity out of secondhand symbols or processes of thought (although this behavior has more complexity and nuance to it, and has more to do with boasting of education obtained at a university level, and classism). There are an enormous amount of college graduates in western society with uniform tatse/clothing styles/mannerisms, with not only identical opinions, but identical expression of those opinions, and identical attitudes.
So, basically, "poser" is an Orwellian word, that instills fear into the minds of teenagers (and some adults), which in turn makes them consume/conform in an efficient manner to avoid being labeled as such. For corporations, this is one of many tactics that help to create a very effective society, where individuals place their own constraints instead of having those constraints come from a dictatorial system.
Kid A: Man, that kid is a poser! He doesn't even know any other Greenday albums besides "American Idiot"
Kid B: Well, you shouldn't be too proud of knowing Greenday albums in the first place, because they aren't a very talented band. I would say they are an embarrassment to punk, but punk was never anything special in the first place. It was all Malcolm Mclaren's ploy to sell clothing in London in the late 70's.
Kid A: Dude, you're faggot!
1.one who pretends to be someone whose not.
2. who tries to fit in but with exaggeration
An Avril Lavigne fan
"Like oh my god! She is not pop, dammit! She is totally punk rawk!"
Any one who does not follow his/her own ideas of what he/she likes. Following no one set norm makes you real and following no one set norm makes you poser. Poser is governed not by the clothes, music, or makeup you wear, but rather by the state of your mind and the conformity to your own beliefs.
Posers conform to the beliefs of others.
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.
some people are posers.
Someone whos acts like someone theyre not,but not realizing that there being fake, basically a loser trying to fit in.
A poser green day fan,this applies to other poser bands--

A poser is someone who tries hard to be something they arent. Usually, posers call other people posers because they are jealous that the person they called a poser is more skater/stoner/goth/punk/rocker/grunge/etc. than they will ever be.
One who attempts to appear to others as something they are not, especially by their manner of dress; a charlatan.
Take off that gold chain Julio, you're such a fucking poser!
