Sure, there are a lot of geeks, but FANBOY is a very specific term applying to an almost religious adulation of a CURRENT pop culture phenomenon. You follow the subculture, toe the company line, support the new media such as movies, books, games, etc., all while keeping the basic mantra of the Star Wars Fanboy:

Lucas is creating his vision!

If you're against the Special Editions, the Prequels and/or the 2004 SSE DVDs, then by definition you are not a Star Wars or Lucas fanboy.. more like a born-again Anti-Fanboy.
