If you're going to be snotty about it, post your preferred definition with a sourced link. Btw, my source was just a little old thing called the Oxford English Dictionary.
That's one thing that drives me crazy about posting on RTB. The posters (at least some of them) don't understand the difference between something like a medical journal or the Oxford English Dictionary and Yahoo Answers. It's really tiresome. "Something you read on a website," right.
And yes, a phrase about "**** running through a tinhorn" makes sense in that instance. Ever heard of a bullshitter? It's another way of describing a bullshitter. Makes perfect sense to me. You do understand westerns were super popular in the time Patton would have said that, right?
You may be right that it could be something else, but there's no reason to be so shitty about it when I'm just remarking on figuring out what a weird phrase meant.
