You may have noticed more people are saying “you guys” to refer to just about everyone.
“Some speakers use ‘you guys’ but it depends on where you’re from," says Anne Curzan, a professor of English at the University of Michigan, who specializes in linguistics. "Southerners often use ‘y'all,’ which I think is a very useful pronoun. And in Texas, for some speakers, ‘y’all’ has become singular, and the plural is ‘all y’all.’ In parts of the East Coast, you get ‘youz,’ or ‘youz guys.’ In Pittsburgh they have ‘yinz,’ or ‘younz.'"
