I've learned a few Rock N' roll moves, one where the girl jups up and sits on my knees with her knees, and another where I sort of, swing her around like a hoola-hoop.
Wish I knew the basics though.

I can not dance and thus, I choose not to.

That's really all that needs to be said on the matter.

I love dancing. It is good fun, and pretty good exercise. In public, I'm most comfortable dancing with friends who aren't trying to impress anybody with their 'fly moves' and 'happenin' 'tude'. When we can all laugh at ourselves, dancing is incredible fun, and we end up doing silly things.

...I believe Azisien can attest to that unique brand of danceable nonsense.

As for formal dancing...

Half a semester of swing (Jitterbug and a wee smidgen of Lindy Hop). I had to stop because all my papers started coming due on Thursdays, and the dance classes were on Wednesday evenings...and I tend to procrastinate on everything related to school.

Beyond that, I mostly do some variation on the two-step for essentially any and all other eras (80s, 90s, hip-hop, club, etc.). Left, right. Do something with your hands while going left and right. Repeat as may be necessary, throwing in head nodding/bobbing as may be required.

I can also do the twist, though that's not a particularly difficult dance to master, and has limited application these days (though it would be fun to apply it to hip-hop/rap music).

I plan on taking up swing again sometime this year, and would like to learn a few more ballroom dances, and maybe pick up some Latin (because Latin dancing has palpable attitude). If I ever get anywhere in swing, I'd also like to learn 'Aerials', because they just look really cool.

Hooray for dancing!

when I dance, it's more like pivoting or swaying to the beat of whatever I'm listening to.

I'm not terribly coordinated, so anything more complex than that and I might be running into people, knocking things over, and creating general mayhem.

Im not allowed to dance, court order.

Dude yes. There's nothing cooler than aerials. Although they wouldn't allow them at our dance practices, because if anyone got hurt, the club might have gotten shut down.

Did you even learn the Charleston at your swing dance class? (I think that's one where you dance in two big lines)

The charleston is both it's own dance and one of the basics in swing dancing, I learned a few passages in Lindy Hop, basicaly, I swung my partner out so we stood side by side and did some mirror morements with hands and feet. It's really fun, especially when you stand right next to eachother, stomach to back, and do the exact same movement.

Good times...

This is only too true. However, given that I am about as agile as a brick wall, I'd probably be the guy who keeps his feet firmly planted on the ground.

Additionally, I think I would fear the woman who could swing me around in the air with ease. I'm not exactly your traditional lithe dancer's build. I'm a series of rectangles squashed into human form.

We were taught by an amusing French-Canadian pair, and learning started (and ended for me, unfortunately) with the Jitterbug. Fun dance, but really frustrating because it's a six-step (left foot: ball-heel; right foot: ball-heel, left foot: rock-step) and swing music is generally eight-to-the-bar, so you really have to think to stay in time.

So to provide a short answer: no, I didn't.

...though having just looked up the dance steps on Wikipedia (the 'Kick-Back Charleston', anyway), it seems a few modifications to the Jitterbug would allow me to perform it...

Still: swing dancing is fun.

And for those who have never witnessed the splendiferous nature of aerials and are confused by the gushing CelesJessa and I are engaged in, here is an excellent and demonstrative link:

If I am only ever half as good as these people, I will be content.
