A form of music usually involving guitars, drums, bass and vocals. Also a dismissive or 'whatever' type statement given when there is nothing else to say, or as a prefix to an equally dismissive or 'whatever' type phrase.
An awesome genre of music that many believe died after the 80s. I say that new rock is good but it was best in the 90s with Rage Against The Machine, Green Day, Red Hot Chilli Peppers, The Offspring, and Metallica.
