I noticed that when I’m on the bus that 99% of the guys on the bus sit there with their legs opened like “hey look my junk”. All the women polity have their legs closed or crossed. Normally I do not care about these sort of things but when the bus is crowed I suddenly see you as the jerk who takes up two parking spaces because you wanted more space for your car.
there are studies
it’s a territorial thing/display of dominance
