A Wisconsin Tumor refers to the infamous "beer gut" that so many men proudly sport. The term references Wisconsin in particular most likely because of the amount of beer consumption and cheese eating that takes place there. Although many males in Wisconsin have the mysterious body shape, this can be seen on men all over the world.
Would you look at that guy over there?! He's balancing his drink on his Wisconsin Tumor!
