My book of sexual positions (I didn't write it, I just own it) calls this position the "super ball" position.
I remember when I was a kid, sometimes I would get a superball from the gum-ball machine at the grocery store. Those superballs used to bounce really high. My mom told us we had to play with them outside, but we lived on a dirt road. Superballs didn't work well on a dirt road. They would bounce in unpredictable directions. I lost a lot of superballs this way.
I've never had a woman tell me I had super balls, but I think I would like it.
If you do this position guys you would be a "super baller".
