The Man Lean

This is what I call it when a dude is driving a car and is leaning so far to the right that it looks like he is sitting in the middle. Why do guys lean like this? You almost never see women doing it. Is it their huge wallet making them do it? It looks absolutely ridiculous. Can't be good for your posture let alone future back and hip problems. Do they walk with a severe lean too? Seriously guys, sit up straight like your mother always told you to.
