I know a guy

My man = You did good.

My guy = That could have gone better.

My brother in Christ = What the fuck have you done?

Now do it with Man-Bat!

Isn't it "gal"? As in guys and gals?

Wo guy let's not jump to conclusions now

Self-entitled

It depends on usage.

"He's a guy." Is gendered.

"Hey you guys!" Is gender neutral.

"She's a guy." Is transphobic.

I think there's never going to be a true consensus on things like this.

A friend who is a trans woman told me that sometimes when people say "hey guys" or similar, she often feels an instinctive rush of dysphoria (especially if it's a context where she's the only woman in the group), but that she realises it is often intended in a gender neutral manner, so it's not reasonable for her to feel upset at this. She considers the upset that she feels at this to be "her problem" so to speak, and doesn't expect people to change how they speak. Since this discussion though, I have tried to be more mindful of it when using words like "dude" or "guy" as collective terms.

Context dependent - i.e. walking up to a group and saying 'hey guys' is gender neutral, but saying 'I saw a guy the other day' generally implies you saw a man.

“Guys” (plural) seems to have two meanings:

• an group of people
• a group of men

“Guy” (singular) doesn’t seem to be gender neutral, so it seemingly only means “random man.”

So, “you guys” can be gender neutral, but if you’re a guy who dates guys, you’re likely gay, bi, pan, or queer.

I've started using folks because I couldn't answer that question

It depends on who you ask, but I think that when you say "guy" most people think of a man.

Kinda, in both cases it's a difference in formality.

More like:

Creepy guy: intimidating, gave me the ick, looked at me weird

Creepy man: call the cops on this man for what he does in his free time

I’m not your man, sir.
