From Silence of the Lambs: Don't flatter yourself, Starling. That was a long time ago. Why would I hold that against you? Besides, this town is full of cornpone countrypussy.
A person generally known for conducting themselves in a "short-bus" manner in outdoor social settings, while completely unaware of the inappropriate nature of their actions. Often found at college football tailgate parties. Sort of a mentally-challenged version of a D-bag.
Cornpone:
Billy: "Man, I'm sorry, I heard you had cancer. So what are you gonna do with your stuff after you die?"
Steve: "That Billy is such a freaking Cornpone."
When you get cornholed by someone who took a big ass cob of corn and sqwoosed it onto their dick. It's no fun...I went to Nebraska one time and a bunch of rednecked motheruckers did it to my dog.
