One who is so obsessed with the music genre "classic rock" that they proceed to declare all other music genres moot. The individual in question only allows classic rock to satisfy their musical needs and refuses to explore other genres.
Guy 1: Dude all your music sucks. You need to listen to some zeppelin or sabbath.
Guy 2: STFU. You are such a classic rock junkie.

When hooking up with a girl who is intoxicated beyond the point of no return, you have the girl bend over and grab the toilet while she throws up, and during her regurgitation you have sex with her from behind as the girl holds the toilet for support.
David: Dude, did you have sex with that drunk girl at the party last night?
Ryan: Yeah dude, I had her doing the Classic Toilet Grab!
Ryan: Yeah dude, I had her doing the Classic Toilet Grab!

Boring, stuffy old music played on irritating instruments like the violin. Made obsolete by superior modern forms of music like Rock, and Hip-Hop.

A really cute dude who just has his life together. He is calm and collected and is a stereotype for everything. If you meet a classic chad it’s not ok to lose him because he’s a real special fella.
