The mirror dancing phenomenon

Best place to witness this weird practice is definitely in Yerevan, Armenia.
However, as witnessed by yours truly the other week in neighbouring Tbilisi, Georgia, this form of entertaining oneself through the mean of dancing to oneself in a mirror seems to have spread around.
From a non-local (quite obviously) perspective this is actually rather hillarious, but in a way a tad ingenious too.
Think about it. You go to a club with a girlfriend of yours. She/he finds someone to dance to, and there you are, left all to our own devices. And if you in turn can't persuade someone to wiggle themselves in tune with you, what better way is there than just to turn to the mirror?
At least the mirror won't give you a funny look when you pull that move you've been dying to try when Ruslana comes on... and, perhaps more importantly, your reflection will never be a better (or worse) dancer than you... it's a total win-win situation.
Of course the said mirror will have to be full-length and preferably totaly cover at least a whole wall in that particular club.
In any case, if somebody needs any help in kitting out their dancefloor, I'm sure the fabulous Björk Þ. (currently in the one and only capital of mirror-dancing, Yerevan) will be happy to share her thoughts, experiences and well-known expertise on the matter.
Brilliant.

There's me wondering if this is going to spread further west, or if this somewhat peculiar practice is doomed to stay in that area of the world.

Your thoughts are most welcome.
