I avoid it.
I don't enjoy it and I look retarded doing it for I have no idea how to. After enough alcohol I seem to occasionally forget that, though only in company I know won't laugh at me(and probably would look as hilarious as I do, if I could see straight), and it happens ONLY if I am dragged kicking and screaming to the dancing area, and even then I last for about half a minute before I sit down and instead drink and/or smoke and/or take photographs of others. I have on one occasion used retarded dancing as a means to keep myself awake, that was when I went to The Netherlands on that Eurohash thing(no, that event has absolutely nothing to do with ingesting cannabis, and yes, I am serious here - google Hash House Harriers if you don't believe me/want to know more about it).
So yes, basically the only way I will end up dancing is after ingesting large quantities of alcohol, among others more or less like me, and will probably give up after a little while.
