One of the best things about being a fangirl or fanboy (though they apparently have nuanced differences beyond suspected gender, which I’ll explain momentarily) is our ability to crush on anyone (and sometimes anything). Hell, the term “fangirl” is now a verb meaning (among other things) to flail wildly, crush, and/or obsess over a character, and this is one of the areas the two terms have slight differences.
While fanboy and fangirl should only denote the gender that the particular person identifies as, their meanings go a bit beyond. Fanboys are usually the ones who nitpick, weed out, and formulate theories about their favorite works and characters. They argue over what’s canon, what’s head canon, what’s non-canonical, and what’s just plain crackpottery/tinfoil. Fangirls stereotypically freak out and flail over their crushes, write fanfiction, swoon over pictures, and create and disseminate gifs and fore mentioned pictures. Both fanboys and fangirls cosplay, and fanboys seem to be more connected with fanart as fangirls are connected to fanfiction (this could also be why fanart is held in higher regard than fanfiction, something I continually critique and that you can read more about here).
By these definitions, I am both a fanboy and a fangirl. The difference is pretty sexist if you ask me, where fanboys are implied to be more interested in the narrative, characters, and foundation whereas fangirls are portrayed as more vapid and insipid. This is sadly common where things girls and even women like are viewed as less valuable (e.g. fanfiction, romance novels, boy bands, etc.), and they’re often mocked for it. If they try to be more “fanboyish,” they’re accused of being “fake geek girls,” *rolls eyes* and the accusers will then force them to prove their devotion in ways that would never be demanded if they were male.
So…I got a little bit ranty and venty.
My point was being a fan of any type usually means you have at least one crush, and Final Fantasy plays host to so many beautiful people, you have the crème de la crème from which to choose.
