In Italian football, gemellaggio (lit. "twinning") is when the ultras of two clubs establish a pact of friendship, become each other's "second team", don't try to kill each other when the teams meet, etc.
I'd like the YF to conclude a gemellaggio with the Red and Black Bloc. A: they're good fans; B: they hate the Tards and the Smurfs as much as we do; C: as that article a while ago suggested, "no-one likes the Nix", so maybe we should make friends.
