Someone who is desperate to be with the in crowd and will do whatever it takes just to earn a bit of attention from someone above them socially who could care less about them. they are also well known to be under peer pressure all the time as they are never themselves but instead a poser. They're like that puzzle piece that looks like it fits but just doesn't go there. they can be seen following the leader of the pack also known as the entourage.

2. Someone who is (usually a teenage girl) and approaches someone that is usually happens to be a teenage boy that becomes famous online by "inventing" a hot trend, dance, or song etc. all the girl wants to do is just to have sex or do other sexual inspired innuendos with him or the close friends of the famous celebrity just to say "i had sex with insert name here". also see groupie or One night Stand
