Just in from Charlotte: A new variation on ‘y’all’?

As a lifelong Southerner, I have witnessed many abuses to “y’all.”

I have seen its apostrophe misplaced.

I have heard it misused to address one person, rather than two or more.

But until recently I hadn’t even considered the possibility of redundant pluralization.

As a friend and I finished breakfast at a local Pancake House, the waitress handed us the check with a cheery “OK, this is y’all’s-es’.” (Spelling suggestion, anyone?)

What a word! More amusing than offensive, at least to my ear. Is it a fledgling neologism — or have I just not been paying attention?
