"After the wedding-feast they began to dance. The dances were varied according to generation... Middle-aged Jews would dance [sic] ‘balgareske,’ ‘kozatshok’, and especially the ‘sher.’" (source)
"He frolicked through every dance step that Moshe had ever seen, and Moshe, who had spent his childhood as a fusgeyer—a wandering Jew—in Romania, had seen a few: horas, bulgars, khosidls, freylekhs, Russian marches, Cossack high-steps." (The Heaven & Earth Grocery Store by James McBride)
