People who disregard (or make up) facts to spread that ATI is better than nVidia.
All those ATIdiots fail to realize the ONLY time ATI actually had better cards than nVidia was when they released their 9xxx series. So nVidia lost once in the eight generations of it's GeForce chip, doesn't sound like ATI has that much to brag about at all.

A term that an ATI-loving loser with no friends apparently defined on urbandictionary.com in a pathetic attempt to 'diss' NVIDIA graphics card owners.
I searched for "ATIDIOT" on urbandictionary and found the biggest joke of definition ever posted on the whole site, probably written by some 25 year old virgin and member of rage3d
