A person who loves the musical genre classic rock, which includes bands such as Led Zeppelin, Pink Floyd, The Beatles, The Doors, ACDC, and The Who. They are uninterested in modern music. Sometimes, they are of the opinion that any new music is terrible, in other cases they admit that some of it is good, it just doesn't interest them. Often times they find themselves pretending to love the new alternative band their friend is showing them while wishing they were at home listening to The White Album. Many classic rock junkies are afraid to admit they are indeed a classic rock junkie for fear of being called narrow-minded.
"Oh yeah, I love Green Day."
"That is such a lie. You're a classic rock junkie and you know it."
