A song written by the band KoRn. Its about when the lead singer,Jonathan Davis was in school and was constantly made fun of and him thinking of all the ways he could get revenge on the people (from the music video it appears to mostly be the jocks) it has inspired many people and they often say it describes their life (me being one of those people) the people who dont get it or understand it are usally the "cool" kids or kids that have never been bullied/made fun of. All in all, its a great song
