It is in dictionaries, at least two.

I’ve heard or read the term at least once or twice along the way, I’ve even muttered it myself.

It might not ever rise to a common enough usage that the big dictionaries list it, or maybe it will.

I probably wouldn’t say it’s frequently used, but probably not rarely either.

The six references provided in that entry are all obscure and none are dictionaries.

By your definition of dictionary. Again, words mean what people who use them intend them to mean. Urban Dictionary and Wiktionary are both dictionaries as far as I'm concerned.

Anyway, Meriam Webster has United-Statesian https://www.merriam-webster.com/dictionary/United%20Statesia...

How do you cope with Modern English previously never having been a language anyone spoke or wrote?

Can I ask what the point of this thread is? Is it because of the single word "often"?

Seems like a waste of talent and energy.

The digressions started with the first mention of the term in question by SSLy, not just the descriptor you mentioned. That user was probably pointlessly baiting, knowing that the nonstandard term would set someone off, which has led to the digressions that followed.

I've been using that term on and off. This was the first time someone came forward saying it's incorrect. I don't disagree with your assessment of my intentions, but it wasn't that usage, it was the politics part.
