She is hoop dancing! This is actually a very popular trick that people try to learn. Hoop dancing is rather popular up north back at my home in Pittsburgh, PA. I have not had a lot of time to practice recently, but hoop dancing is something I rather enjoy myself! It involves a while lot more than swirling a hoop around your butt....there are some really intense tricks you can learn. Not to mention it is rather sexy! I can try to dig up some old videos of me doing it. Or some of you lucky gentleman may be lucky enough to see it in person, if you ask nicely!
