This video was taken (not by me) inside Cong, Khal Chasidim (in Chicago) Motzei Shabbos at their Hachnosas Sefer Torah. Dancing are HaRav Michel Twerksi, his son (and Rav of the Shul) Rav Efraim Twerski, and HaRav Michel’s oldest son Rav Benzion Twerski. HaRav Michel is doing, what is know as the “Yud-K..dance”. According to my son, who attended, the event was packed with hundreds of people.
I’m not convinced that’s it… My rov does it every simchas Torah, it’s crazy!
It’s also know as the “Baal Shem Tov’s dance”.
I went to the march, but didn’t go inside.
