A deragatory term for a person who, in order to fit in, conforms to a popular trend contrary to their actual beliefs. Their overall presentation of themselves differs VERY much from who they actually are. the person most likely believes that their true interests would single them out. these people are sad things to see in society as most of them lack pure creativity and life because they have other people think for them.
Person: It saddens me to see that Allie has become such a poser.
