Fraternity guy who tries to be hip but can't because... well, because he's just a lame fraternity guy. A term more from the 1960s and early 1970s. Probably a combination of beatnik or peacenik and frat guy.
At a Dylan concert in 1969.

Me: Aw shit, man, look over there. A bunch of fratniks.
Drew: What?
Me: Over there -- fratniks.
Drew: What?
Me: (pointing but not saying anything)
Drew: Aw shit, man.
