Honi soit qui mal y pense. I'm a Gracie booster. The term can be used in either a positive or negative light, depending upon the context. Contra your Wiki reference, I was not utilizing the term as a pejorative, but primarily in the sense of a Midwesterner who looks strong and healthy, which I think should be fairly clear from the manner of its use in my post. A hick? No. "Uncomplicated" is probably closer to the image I was trying to convey. Porky? Definitely not. My description of Gracie led off with "pretty". The nuance I was reaching for was the solid good looks of a New World valkyrie.
Man, I love this board. To have someone invoke "Honi soit qui mal y pense" (which keeps autocorrecting to "pens") is so cool. I agree that Gracie has a freshness to her that makes me agree with your use of the term "corn-fed."
