A nu-metal band, most popular in the late 1990's and early 2000's. Famous for their legions of highly-defensive fans who write long screeds assuring the world that they (the fans) are not goths, poseurs, thirteen years old, suburban kids, wannabes, Hot Topic shoppers, stoners, or otherwise useless globs of angst and conformity; and that the band is, or is not, "nu-metal", "hardcore", "mainstream", "tru-metal", "alternative metal", or any number of other meaningless, media-created subgenres used to further divide "the consumers" into more-specific (and thus, more easily marketed to) categories.
"Hey, did you read the Urban Dictionary entry on KoRn?"
"Yeah, I did. Jeez, are they defensive much? I mean, you can get info about the band, sure...but you've gotta click thru pages and pages of 'OMG i aM nOt a HotTopic goTh waNNabE!!!!!! and N E way KoRn iz NOT 'nu-metal bcuZ...' It's easier to just go to Wikipedia."
