I came across this video of a tailgating game called Cool Toss. From what I can gather it looks like a bastardized version of cornhole using cooler tops instead of game boards with holes in them. Apparently the creators of this game rolled out the coolers before the Baltimore Orioles opening day at Camden Yards, gathered a crowd, offered up some free beer and rolled the old video camera. They even have a website as you might have guessed, CoolToss.com.
