Reply To: What is the inyan of a mitzva tanz?

I would submit it simply is the point of dancing in front of the Chosson/Kallah after bentching, as the citation brought. Whether they use a gartel, shtreimel, shoelaced shoes, or flip pancakes and make jokes during the dance is all secondary and not the ikkur. But the ikkur idea itself of the mitzvah tantz today comes from the Virti Machzor.
