It was in a restaraunt near the Poconos I first heard Youse guys...thought then it was hard to say the two together...sounded like poor english until obvious more of it was used along the way.
Moving inland to Western Pa. someone mentioned “pop”...had no idea they met soda! Ha! sounds so funny..PoP.
The to Western border of Ohio it became you-ens.
“Pop” is the standard term in most of western Virginia also. East of the Blue Ridge, it is generally “soda.” Which one sounds funny depends on which one you grew up with, I suppose.
