I like the use of “guy” as unisex. Like the word “dude”

He’s a dude, she’s a dude, they’re all dudes

I use “guys” plural to refer to any group of people, including all women/girl groups. I know saying “that guy” still means “that man/boy” but I’m hoping people will adopt it as completely unisex

A guy can dream (I’m a cis woman btw)
