I’m a Northerner born and bred and have never lived in the South. I say “you guys” when I need a second person plural, not “you-all” (or “y’all” or “yawl” or however you’d like to pronounce it).
But I realized just the other day that I use what seems like a close relative of it: namely, “who-all.” As in, “So you went to the party. Who-all was there?” (Which I do pronounce as two distinct syllables, emphasize on the “who”–“WHO-all was THERE?”) The implication being that more than one person was there–in a sense, it’s a “who”-person plural. I wouldn’t ask"Who-all was your seatmate on the train?" if there were just two people to a seat.
I’m curious if anyone else uses this expression. And if so, how they pronounce it. And where they’re from.
