Say what??

How many sayings do I have that could pretty much be considered Ohio ebonics? Does anybody else talk like this?:

I was driving down the street and noticed a lady waiting to pull out into traffic. In my opinion there was plenty of time to pull out and merge, but she kept waiting.

I turned to my wife and said, "You see her? She coulda been done gone!"

..."coulda been done" ??? Am I the only one who says that??
