It means the idea that there is a group of people, an "elite class" that has either the natural aptitude or simply superior training/education, who should be the ones who rule/govern/etc. In MMOs it's used to refer to players who are at the "top" of the game due to either natural skill or practice, telling others what they should do within the game because they have reached the highest tiers of success/ability/whatever themselves. Like all popular terms on the Internet, past a certain point people just start applying it to anything and everything they don't like because it has a negative connotation.
Pretty good summary. I was just going to say someone who thinks they are better than the person playing alongside of them, when both are good. I think your explanation is top notch which puts you in a different class than I. Are you elite? Lol kidding!
