An act performed when one partner eats a massive amount of Wisconsin Cheddar Cheese (making his/her shit very slippery and light-colored) and takes a huge shit on another partner's chest, then rolling it out flat with an empty beer bottle (sort of like rolling out cookie dough).
Did you give her the ol' Cleveland steamer?
No dude, the Wisconsin steamer. I used a beer bottle instead of my ass.
That's how we do it in Madison!
