A little Google-fu brings up this:
Cornhole or Corn Toss is similar to horseshoes except you use wooden boxes called cornhole platforms or boards and corn bags instead of horseshoes and metal stakes. Contestants take turns pitching their corn bags at the corn hole boards or platforms until a contestant reaches the score of 21 points. A corn bag in the hole scores 3 points, while one on the platform scores 1 point.
LinkDon't know about anyone else, but I'm not playing a game called "cornhole."
ETA: Damn, someone beat me too it.
