Flying sugar? Or is it cycling sugar? Spazzy trash bags? Stinco, stinko, what the hell is that? It's powdered sugar (why it's velo I have no idea, maybe because you throw it into the air?) garbage bag (from spazzatura in Italian) and stinco (shin in Italian as in the shin of the pig, football shinguards are parastinchi) all odd names in English but perfectly understandable in Italian. You get the hang of it after awhile.
