[Justin Bieber]

A term coined by Douglas Rushkoff in an episode of PBSs Frontline entitled The Merchants of Cool. Mooks are archetypal young males(teens-early 20s) who act like moronic boneheads. They are self centered simpletons who live a drunken frat-boy lifestyle(or are frat-boys). Examples can be found anytime someone watches Jackass. Rushkoff claimed that the media glorifies this ideal and stifles natural self expression, however, some people might argue teenage boys have always acted like morons(its actually a long-standing stereotype). Nonetheless, standardized conformist dumbass-culture behind a veneer of exhuberance is a scary notion indeed.
Opposite of Mooks are [Midriff]s; oxymoronic innocent skanks who are modeled after Britney Spears.
