look up any word, like plopping:
Those who are devoted to the style of music known as progressive. These people are so devoted to this style of music they sometimes emblazon their clothing with the emblems of their favorite bands. (Pink Floyd, Dream Theater, Yes, etc)
George is such a prog-head he sewed the Dark Side of the Moon Prism on his converse! and Matt drew the dream theater emblem on his pants!

A progressive rock fanatic.
Progheads are not pretentious!
