I guess, especially ever since I bought the Story to Screenplay Book, I've been using certain expressions even more. Most of my fellow workers, of course, don't have a clue about what I'm saying, and I kinda like to keep 'em guessing a bit.
I find myself saying "Tell you what" a lot, especially when I'm trying to emphasize an important point.
Of course, when I'm a bit upset with someone, "Son of a whoreson bitch" seems to just slip out. A lot!
When things just don't seem to be working out, "If you can't fix it, you gotta stand it", is my usual response.
And sometimes, just to tease someone, especially some of my closer friends, "I wish I knew how to quit you" just flows off my tongue.
Naturally, I try to say all these things in a 'Wyoming with a smattering of Texas' accent.
There are probably more, but I'm sure others have much better Brokieisms to share.
