A genre of rock music consisting of bands from the 60s, 70s, and 80s. A genre most people today put upon the highest pedestal, forcing others to accept their opinion that it's "the greatest music to ever be put on a vinyl record" or otherwise. I like classic rock myself, but I don't shove my views on it down other people's throats.
Person: Yeah Green Day! They're awesome!
Other Person: WTF IS RONG WIT UR HEAD U STUPID FUCK. CLASSIC ROCK IS THE EPITOME OF ALL MUSIC U DOLT. ACCEPT IT.
Person: Jesus Christ chill.
