Euphoria? Not for me, although I like to dance, and as a method of meeting women it has huge advantages, not least being the number of men in the "I don't dance" group who take themselves out of the running.
But as to euphoria, judging from the look on the faces of those Birkenstock/long dress wearing, stuck in the 'sixties "helicopter dancers" I see at outdoor concerts, it does apply to some people.
