Do you grok?

What if I said, "Tha sumbeetch sulled up on me."

Sure. "Tha sumbeetch..." is a colloquialism and should be used with a light hand, but what about "sulled up"? I was surprised to learn that not only is it apparently a recent addition to our language but it's very localized regionally.

What if I said the mesteno sulled up? ...probably not a fair question for anyone who's not old-school southwestern.

I love listening to Red Stegall, not just his music but his poetry as well. It's full of good old western flavor that you can't really find too many places any more, except maybe in some of Marty Robbin's old cowboy ballads.

Does it still mean the same thing it did a few years ago, if you pull out the makins and roll a quirly?

These dialects and flavors be used to define cultural differences and locales in other-world locations? Is there anyone who doesn't know how TANSTAAFL works?

I love the flavor sprinkled in - these are the things that really make it sound like home, but at the same time I know we can't alienate non-local readers. Where do you draw the line?
