Mook

In the PBS frontline documentary, The Merchants of Cool, a mook is a marketing classification. It is a classification of a male "Characterized mainly by his infantile, boorish behavior, the "mook" is a perpetual adolescent: crude, misogynistic--and very, very, angry." In Miriam online dictionary I found a different definition. It said "a foolish, insignificant, or contemptible person." I noticed that Frontline described a mook as an American male but the Miriam dictionary only said a person.
