xerox star 

A pop/rock star that is manufactured and pumped out as if from a xerox machine, i.e. Ashlee Simpson, Aaron Carter, or any American Idol. They are highly replaceable and seemingly identical to the others before them, hence the term 'xerox'.

That Xerox Star Ashlee Simpson can't even perform live without a machine singing for her. She's also mildly retarded.

Xero The Beast 

A vile fiend that was forged from the hateocity( I think thats a word...) of all the haters in the world. It was created back in the early years of the Oakland Raiders football carrer from the hate that the fans emmited. Since that day, the beast has gotten stronger. Feeding on the hate that ungrateful fans give people like Ke$ha and Lady Gaga. And now this.. The hatred for that faggot Justin Beiber.

This amount of hate will increase the power of Xero the Beast to gargantuin levels. It will come out of hiding and finally defeat Chuck Norris. Just like the Mayans predicted would happen on December 21, Y2K12. So basically we're all fucked and it's that gaywad Justin Bieber's fault. Oops that comment only made it stronger. My bad

Xerox 

The word "xerox" is commonly used as a synonym for "photocopy" (both as a noun and a verb) i.e. to make a copy with a Xerox photocopy machine.

Xerox was founded in 1906 as the Haloid Company, changed their name in 1958 to Xerox and came to prominence in 1959 with the introduction of the first plain paper photocopier using the process of xerography developed by Chester Carlson.

The novelty and popularity of the Xerox photocopiers made them a household name in the USA for decades after.

While the "xerox" word is commonly used as a synonym for "photocopy", the company Xerox is concerned about the ongoing use of it, because it put the brand name in danger of being declared a generic word by the courts.

From Kojak: Season 1 - Episode 8 "Dark Sunday" (1973).

Kojak: The map you gave me, I had it xeroxed and gave the original to Valano to put into Arties room.
