Sadly, this sort of "liturgical dance" exists in the real world. It would be riotously funny, if it weren't tragic. It's almost universally very badly done; one of the prerequisites for being a "liturgical dancer" seems to be utter incompetence at dance. And here, I speak only of the female liturgical dancers. The male variety are unspeakable.
. . . it's been my experience that liturgical "dancers" are the ones who couldn't find a gig anywhere else.
I've never actually seen one who had the slightest competence in her (thankfully not 'his') chosen field.
I made such merciless fun of our (Episcopal) rector after he invited one of these silly women to do her thing, he never did it again!
No such nonsense goes on in our Catholic parish, and would probably occur only over Monsignor's dead body.
