To define something as "cooler" than the norm. Originally used for outrageous sports and death-defying stunts, "Xtreme" has managed to find its way into nearly every marketing campaign in America: deodorant, beef tacos, soft drinks, and even duct tape (I swear).

When a reply to a tweet gets more likes than the tweet it was replying to, usually indicating the unpopularity or stupidity of the original tweet

This can describe anything in any positive way, really. It just sounds really dumb, and if you use it in any context, everyone who hears you will assume that you're an emotionally handicapped chimpanzee.

One better than "Extreme". Only those willing to take things to their furthest would dare do something so extreme that the "E" at the start of the word is too shit scared to stay and watch, running home to it's mum.

A marketing ploy targeting the 13-17 demographic, in which ordinary commodities are presented to our unwitting youth as "crazy" and/or "totally awesome!" when in fact they are just pumped full of blue and red dyes and packaged in shiny bags.

stupid way of spelling "extreme"

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.
