People that conform to 'new' trends that are viewed as 'cool'. In return these people are accepted by acting like one in the crowd of unoriginal 'self' social ruling and ignorant people. This is mostly seen in High School where only certain looks and trends of music are conceived 'cool'. This leads to unoriginal one minded thinking. These people have no personality of their own other than how well they adapt to mainstream culture.
Look at Selene, she's trying way too hard to be a "mainstream fag".. Dressing like Lady GaGa.
