"Corn toss" my
buttfoot! It's "cornhole", easily verified by driving through Cincy, or many small towns is SW Ohio, and looking at the bars, many of which advertise "cornhole" tournaments. BTDT. When visting friends in that area, two years ago, I was ROFL the first time I saw one of those "Cornhole Tournament" signs ... they had to explain. I got to be pretty good at the game, during that visit.
BTW, if you follow British usage at all, "Corn Toss" isn't much better than "Cornhole".
