A game which originated in the state of Maine, in the United States of America. The game is continuous, much like The Game. The first person to tell someone else that they are a CheeseMongrel wins, but then no one else may say the word until the next day.
Gene: Hey Casey, you're a CheeseMongrel!
Casey: I already said it today. Try again tomorrow.
Gene: Aww man...
Casey: I already said it today. Try again tomorrow.
Gene: Aww man...
