This word is used to describe someone who listens to classical music, but rubs it in your face like a cunt to give you the impression of their snobbishness. I know this because I myself am a listener of classical music, but with today's pop music, I can only blame the listeners of that stuff; not all classical listeners are classicunts.
Zomg, look at Tom over there, listening to Shostakovich and Schumann on his iPod. He really used to like metal, but now thinks he's better than everyone else because he listens to this music; what a douche!
A pun on the 'El Clasico' football game played between Barcelona and Real Madrid, 'El Clasicunt' is a game played between two despised rivals of your own team.
Initially coined as a suitable name for the game between Oxford United and Gillingham FC, two of the most disgusting football clubs on the planet, and rivals of Swindon Town FC. Could equally be applied to any combination of games between the teams already mentoned plus the Bristol teams and Reading.
Oxford are two nil down at Gillingham already in 'El Clasicunt'.
