The name "Big Bertha" comes from a giant Pre-Nazi German war cannon that would lob 1,800 lb explosive shells into shit like France and Belgium. It also happens to look like this bitches dick.
First off, this chick is drunk off her ass, and I mean that in a literal sense. She had a gallon of wine.. directly through her asshole. Now I always thought it was fun to poo on the floors of public restrooms, but this lady takes it to an all new level. If you've ever played Command & Conquer, think of her anus as the Ion Cannon.
