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.
I believe her first mistake was LOL'ing while getting passionately bulldozed by a 17 inch yogurt slinger. That kinda laughter tends to translate to one thing only - "your ion cannon does not phase me, please bash my ovaries harder". Invitation clearly accepted.
