Very similar to conformists or popular culture... but actually a subculture of pop. If sixty kids shop at Hot topic then they are mass-marketed non-coformists. They used to listen to Marilyn before he released "AntiChrist Superstar" so they justify that they are not posers. Next gen version of these kids are know described as Scene.
Choir of 13 angst-ridden kiddies singing in unison:
"one is different but there are a million the same!"
After seeing this specticle one realizes...Holy shite!
All Those kids are practicing mass-marketed non-conformism!
