The ORIGINAL X Factor. People on Xtreme are the sickest of sicknasty. They also respond to the name Sigma Fackers NAF's. Xtreme is xtreme to the 5th degree. They often use expressions like noice and croicky in Austrailian accents. It is tradition to vandalize yeards late at night with toilet paper(but of course xtremers remove the cardboard roll). Xtreme cannot be defined in english or any language for that matter because to define xtreme you must use at least 60% of your brain,which is not possible, therefore understanding Xtreme is not possible for humans since a human only 20% of their brain. They often say their names backwards and wear black and lime green attire. When xtrememers are out to play make sure you lock up your kids.
