Hi there. I have a doubt regarding the word "guy": I thought that the plural form could also mean "people", including women and not only males (and that's what wordreference dictionary seem to state, too), so a couple of days ago I said to a group of English young people I know: "How are you doing, guys"? and one of them, a female, answered to me: "can't you see we are not all guys?" (well, I don't remember the exact words, but more or less that's what she answered). So, how does this word works? Can "guys" mean people including males and females or not? Or does its meaning changes depending on the contest? Has it a different meaning in American and British English? Thanks in advance for your answers.
