A form of music. It combines metal, alternative, hip-hop, and various other things to create what is in large part talentless garbage. With the exceptions of a few decent listenable bands(Deftones, Korn, Chevelle, System of a Down, Slipknot) is pretty much complete shit. 99% of these bands put too much effort into their look, repetitive angsty lyrics that have no substance, talentless dropped-D,Db,C,etc tunings, shit drumming, turntables, rapping, and being accepted with the norm. These bands also have talentless guitar parts which if listened to more than twice could actually destroy nerves in your brain. The few good bands in this genre defy some of the rules of numetal and aviod sounding like everyone else. However others are repetitive, sound like everyone else, and basically can corrupt your soul. The people who listen to it are mainly kids who live life fine yet act pissed off and "relate to" the garbage lyrics of it(which all sound the same and are all about hating people for some stupid reason). They buy chains and clothes from Hot Topic, and aviod true metal at all costs, believing that they are "hardcore" by listening to dumbass Disturbed-like bands. While true metalheads listen to actual talent(Slayer, 80's Metallica possibly including the Black Album and less likely including Load+ReLoad, Megadeth, Anthrax, Testament, Dream Theater, Pantera, all bands with great talent and unique qualities). While some numetal is decent, possibly even good material, it cannot be taken extremely seriously or the evil of the bad numetal might take your innocent life.
