As I said, I’m a 5th generation Texan and I’ve never heard it used. Where are you from?
5th generation Texan, huh? So am I sugar. Not sure what part of Texas you hail from, though I’d guess Austin. All ya’ll is legitimately and unarguably Texan.

Simple Uses of “You” and “Y’all”
When referring to one person, use you.
When referring to two people, use y’all.
When referring to three or more people, use all y’all.
Note: Under no circumstance should you use “you all” to refer to two or more people. It should also be noted, that “all y’all” can also be used as an intensifier or a designation of emphasis, not merely a reference to a plurality of persons. In this case, “all y’all” is something akin to this: “All y’all better listen up, if this mess doesn’t get picked up—and pronto—I’m going to clean all y’all’s plow.” If you get really rilled up you can use the triple-dog dare of “all y’all”: “all of y’all”—but use this sparingly, it is the equivalent to weaponized uranium in the Texas lexicon.
:: I’ve never heard it used. Where are you from? ::
The United States.
Why ya wanna divide?
How bout “wallago” surely every true Texan has used that from childhood.
