I had only heard the term varsouvienne as a particular dance move. In a waltz, holding both hands, you rotate such that your hands make a window - I think you're looking over your shoulder at yer partner. I haven't danced for ages, and even longer since I had a parther with flashy danc moves. Someon more au courant can, no doubt, describe it better!
