we actually are kind of fed up of spinning on the bull's balls, especially because there's a long queue of tourists, but it's fun and it's supposed to bring good luck and fertility. so why not! if there's no one I still do it!
Because it's one of the strangest traditions in Milan. You have to go to Galleria Vittorio Emanuele, go more on or less in the middle of it and you'll find a lot of people spinning on the poor bull's balls. Just take a look and do it!
The proper way to do it is to place your heel firmly in the bull’s groin and turn backwards three times.
