mannaggia alla sacra sindone

Another, less common, form Italians use to imprecate in moments of crisis. It is one of the most powerful insult to deity in the story of humanity. Actually, it is almost not used, because it's too long, and you wouldn't say that instictively: porco dio o mannaggia alla madonna are more practical. But, using it in a proper manner, given the fact that you actually HAVE to think of saying it, can make you (yes, even you, and me, who navigate this side, a really cool aura. Also, Sir Paolo Chiavator, the creator of Harry Fotter (this is the original, Rowling stole the idea from poor Paolo) would be proud of you.
