vainstream 

the large masses of dis-likable loud douchebags/sheeple that are among us. the vain mainstream. that whole "me!! me!! mee!!!" mindset of "trends" and "pop music" and stuff.

"ugh i hate vainstream. they're so self-absorbed"
"pop music/artists is/are just an exaggerated and money-making form of vanity. they're the vainstream"
