Fanboy. It's simultaneously the geek equivalent of calling somebody a racist on the internet and a badge of pride, the ultimate declaration of one's undying devotion to some greater entity. Are you a fanboy (or fangirl)?
Do have an unconditional, irrational, deeply abiding affection for a company, product, person, or other cultural object, so much so that you consider yourself a fanboy? Or is that taking things too far?
How do feel about fanboys?
