What the heck is this "dancing" thing and how do I do it?

[Ghost Nappa]

I'm going to some sort of dance in like about three hours and I never really bothered learning how to dance but I really need to know how so I don't just stand at the sides or if I do try, so I don't embarrass myself in front of everyone there. I'm pretty sure there are some dance gods somewhere in this forum. Please help.

Edit: Never mind, I just watched a couple YouTube videos and that was helpful enough. I don't know why I didn't do that in the first place. But feel free to teach me new things if you'd like.
