Many of today’s most diffused youth cultures come from the United States which, in latest decades, have conveyed these styles helped by innovations in communication field. These include two of the most emblematic and important for this kind of subcultures: the Internet and MTV. Indeed, youth cultures often make use of specific stereotypes related to the music, the type of clothing, interpersonal relationships and lifestyle. Many of these are negative, extreme and rapidly changing, it is therefore difficult to obtain a true portrait of the current youth movement.

The term Poseur (or poser more commonly) used in the last years more and more frequently on the Internet, was born as epithet used to describe certain subcultures, more or less correctly, a person who does not belong to a certain music movement, but rather he pretends to be an integral part of it, for example simply dressed, according to data from that movement, without really know it.

While in common use this word has taken multiple meanings, it was originally created to describe the attitude of few people, often similar to members of a music scene, careful to details, to the look, engaged to appear something they are not . This trend of young people has lately exponentially increased on the Internet, because the network allows you to appear through the identity that you desire. In fact, with the proliferation of social networks (MySpace, Badoo, Facebook, etc …) that allow you to create an identity and a self-celebratory profile, even without having any particular skills, were born many pages of “poser users" with every pictures made ad hoc, pages studied in detail (but making everything seem spontaneous and real). And here should be taken over the famous dilemma: is it better to be or to appear?
