Depending on where you born, that is how you would say the phrase "you guys." Since I was born in the South, but raised in New Jersey, I'd say "y'all" or "you guys" (I don't say youse guys, that just feels weird.
Strangely, I'm from the 'you guys' area, and I say "y'all". That is totally me now. I'm from the western part of the u.s where they say you guys but now bcuz of Texas I say y'all
I'm not ashamed. I come from the ONE state circled on the map. Yep, I used the, "Yous guys" but now I'm more of a "ya'll" gal.
Yinz/Y'all/Youse guys- Hey thats Pennsylvania for ya. I prefer y'all.
