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

A poser is someone who tries to fit into a profile they aren't. People who try to give off the impression that they are one thing when they are really another.
Also, a poser can be one who says they can do something that they can't.
Or more commonly, a poser is someone who, when doing something successfully, takes more than enough credit for it.

2. who tries to fit in but with exaggeration

A person who attempts to blend into a specific social group.

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.

Someone whos acts like someone theyre not,but not realizing that there being fake, basically a loser trying to fit in.

A poser is a girl/guy who listens to a certain type of music or dresses a certain way to impress people or to fit into a certain crowd. often times people get mixed up with those who are posers and those who are not. If you go out buy a sk8r-boi sweatshirt and a skate board and go out on the town and ride around and some one shouts out " fucking poser" are you one ? NO! Come on people..you went out and bought the skateboard so you could...erm GET BETTER! Seriously how are you ever going to become a skateboarder if you dont practice and get better? *cough exactly* now in a different situation. Lets say you go out buy a skateboard...by the way you dont even know the brand of the board and you go out with your friends and just sit there while they do there little skateboarding tricks ... so basically you are just there to look cool..then are you a poser. Yah? yes!
