Oh gawd, it's usually pissing on a Ford or Chevy symbol. I don't know when it became prolific, but I always imagine these are the guys who also spit out their windows.
Please be offended if I've offended anyone.
My ex and I laughed and laughed once when we met a friend of a friend, and the friend of the friend asked my ex almost very first thing: So, you a Ford man or you a Chevy man? Um...I don't know?
