Hi guys, I have a question: one of the Divination books Harry notices at Flourish and Blotts in PoA is called "Broken Balls: When the Fortunes Turn Foul". I'd like to find out what the expression "broken balls" means here. Are they crystal balls? Or some, er, different kind of balls :-)? This is needed for a translation. Can anyone help me with that? Thanks :-).
