I woke up to the smell of musty cheese, only to see my friend trying to give me a Wisconsin Sledgehammer
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 WisconsinTumor!
When a male, during sexual activities unloads semen onto his partners chest, then the partner must go outside and tan, they semen will then create a very neat tan line
