Not most Americans say "ya'll" only mostly people from the south.. trust me, I was born in the north, and raised in the south. Up in the north I remember everyone used to say "you guys" instead of "ya'll"
My grandma is crazy she used to call her couch "the davenport" and everyone in ohio seems to call coke, "pop" so she's like..
"Would you guys like to sit on the davenport and drink a pop?"
