and my new favorite anti Milan (ok the Milanista chiacherone is beautiful) is the old classic "chi non salta insieme a noi cos'e... e un milanista... pezzo di merda!" That's a pretty standard one in Italian stadia, Torino for example have it for the gobbi ("gobbo di merdaaaa... gobbo di merdaaaa... lovely one
) but it's the first time I heard it from us. And it was beautiful.
I can only find it here in decent quality, at the beginning. Roughly 2:30 minute mark, but screw fast forwarding, watch the whole thing, it has the most perfect timing possible
