Didn't realize this was a skill :)

*clattering of hooves intensify*

What manner of sorcery be this?

Of course

I can but not very easily. I always wanted to cross my legs in class under the desk but nope my legs had other plans for me. So yes physically I can do it but depending on the situation it is not always feasible.

Is this a thing now?

Yes but not yoga style, just normal.

Yeah. You know guy's balls are designed in such a manner where they rest on top of your legs if you cross them, they can even go up and inside your body. So if you're thinking that's why you asked the question, you now know.
