Y'know how Prosciutto uses his legs to attack not his hands? He barely moves his hands around in the Italian way like Ghiaccio, Risotto, and Illusio too. Well y'know who else uses their legs to dance in large steps here and there? Russians.
Anyways, Russian ex ballet dancer Pros

Prosciutto throughout the TGD fight:

Prosciutto and his Russian huge leg movements. He swings them so effortlessly. Most Italian, Spanish, French, and English leg movements in dances are in small steps.
Now look at Prosciutto's leg moves and hip sways and tell me he wasn't once a Russian dancer.
