This is a flu you will get when you fly to Green Bay Wisconsin and wear a 49ers jersey to a local restaraunt. Flu entails vomitting, massive diarhea, and the inability to make it to Lambeau Field on game day.
I flew out to see the niner packer game, but got Wisconsin Cheese Flu and spent all of sunday crapping on my best friends couch.
