1. (adj.) one who steals or copies another person's ideas, thoughts, words, or actions and attempts to pass them off as their own.

2. (adj.) someone who pretends to be of a certain group of people in order to become more popular, look cool, or fit in.

3. (adj.) a sorry sucker who is only believable enough to fool themselves and the other poor bastards who fall into the same category.

4. (adj.) a human being with low self-confidence or high levels of immaturity who believe that by living a lie, they will be able to redeem themselves for who they trully are.

The usual lot of posers nowadays include anywhere between tween, pre-teen, and teen. They are made blatantly identifiable by there over the top make-up, hair, costume, action, and 'persona' developed in order to insinuate themselves into whatever category the poser is attempting to infiltrate.
An official dead give-away for a poser is the afore mentioned appearance. But one of the most tell-tale signs of a poser is the fact that they really have absolutely no idea about whatever it is that they are trying to imitate. Simply, they have no understanding of it, and fly by on the bare-bones of knowledge they have probably gathered swiftly over the internet.

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 - 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.
