Question

I keep reading this term in fic written by americans, and I still can't figure out what it means. What the hell is "Indian-style" referrring to when someone is sitting down?

Is it cross-legged? Sitting on your heels? What? Because, really, if you're sitting on the floor, there's only about four ways to sit. Cross-legged, sitting on your heels, sitting with your legs up in front of you, or sitting so your legs are folded off to one side.
