There are so many good suggestions. Several of them repeat themselves; that should be a sign they'd be useful for people.

This is a good thing!

And, in the spirit of hopefully keeping things calm and friendly, I'll gently attempt to help with the "aggravated" term, as both sides have a point...

Colloquially, the word aggravated became acceptable to describe the state of exasperation or annoyance, well over 40 years ago, here on this side of the pond. (I am referring to a Webster's New World Dictionary of the American Language, College Edition, from 1968.) That means it does not indicate substandard or illiterate usage, and is perfectly acceptable in informal, conversational settings.

Language changes, and sometimes those changes are natural, legitimate, and preferably shouldn't be used as a point for splitting hairs, but for advancing communication and concepts.

Plus, we already have words on the list which are not exactly in the form of the King's English!

I see this as a chance for a few giggles, and for getting some needs met, in a small way.

Let's have fun with it.

So, I will suggest some more:
