On the topic of crossing legs
It means nothing except how different people are comfortable when sitting or reclining. However, check the places on your legs, regardless how you cross them, because you'll most likely discover a bump where the blood vessels, that have been pressed against one another for years from crossing legs, have blasted their internal valves and resulted in varicose veins. Note: a varicose vein does not have to be an ugly blue/black thing adorning your legs. Just a nice sized bump is enough to qualify.
Now, aren't you all impressed?
