“GUY” IS A GENDER NEUTRAL TERM.
Yes, yes it really is.
The term “guy” is a colloquialism that evolved from people referring to punks, hooligans, and other “unsavory characters” as Guy, in reference to Guy Fawkes. It was a reference to his rebelliousness and radicalism, not his maleness. It actually originally had no gender-based significance. This is why I hate it when people are all like, “But you’re a girl!” when a girl refers to herself as “this guy” or some such. And when people equate the word “guy” with “has penis”, even though that’s pretty much what it means in modern usage. But it shouldn’t. Because it’s a friggin’ awesome word and other people should be allowed to use it. Not that this is radically important or anything. It just bugs me.
