"Shiraz" is the name of a city in Iran. If you check out this website...

...you will find that it says that the city was named Shiraz because of "its similarity to the stomach of a lion (Shir in Persian)."
So, presumably, "Shiraz" means "having the stomach of a lion". Whether that's a literal or a figurative meaning, I don't know. If it's figurative, then I would say that "Shiraz" could be a name to denote courage -- or a dangerously carnivorous appetite. :)
