In reflecting on time spent both on and off the dance floor, I realize that I’ve only “Waved my hands in the air like I just don’t care” when encouraged to do so by a DJ or a professional musician of some kind. 

It’s a pretty sensible chain of causality: you wave your hands in the air because, well, you just don’t care.  Intuitively it makes sense.  Emotionally it feels right. On the dance floor it’s unquestionably the correct thing to do.  I simply never do it anywhere else.

So I think I’m going to make a change and try to incorporate this activity into other areas of my life.  For example, an executive might say at a meeting: “This project is absolutely crucial and it affects all areas of the company.  Greg, what do you think about publishing a detailed timeline on the corporate intranet so everyone can review it and take note of our progress?...okay, what the hell are you doing with your arms?”
