rock 

1. The best genre of music. Contains meaningful lyrics and awesome guitar/bass riffs backed by drums. Way better than hip hop which is just "YO NIGGERS HOES MAD BLING BLING BITCHES".

2. A good genre of music. But if you listen to it, the ditzy slutty popular girls have 34 boyfriends in 2 days and listen to pop and the jocks that listen to gangster rap and think they are black will call you "pussy" "mosha" "uncool" and various other names.

The best rock artists are AFI and Chixdiggit.

Rock 

A genre of music stolen from blacks by whites. Ranges from the great, (The Beatles, Stones, Zepplin) to the horrid such as metal (guttural moans and mindless powerchords), emo (whiny bitch music), and punk (gotta love feedback and grossly detuned guitars!) Don't even get me started on shit that was made within the last ten years! (Pop Punk, Nu-metal, rap-metal, etc.) All-in-all, a decent genre that lost a lot after the 70's

(good)Rock is dead...Long live rock
