I admire the nerdly way you've framed this question, but nightclub dancing doesn't work that way. Performers on stage or in videos have choreographed dance sequences, but people dancing in clubs just move to the beat, any old way they feel like.

When I started going to clubs, I fell back on the ballroom dance steps I'd learned in my teens. That was sort of overkill, but it gave me something to think about until I conquered my anxiety. Just move your feet to the beat, keep your upper body relaxed, and don't think about it too much - nobody else is!

If you keep dancing you will develop more of a vocabulary over time. Watch what other people do, maybe add a little of that flavor to your own motion. Then shut your eyes and see what feels good. Don't take it too seriously.
