According to Merriam-Webster, a turophile is a connoisseur of cheese, "a cheese fancier" it says and in essence, a lover of the creamy rich calcium aphrodisiac known as cheese. Turo is from the Greek tyros for "cheese" and -philos for "beloved" or "dear". For the proper pronounciation, go to Dictionary.com here.
The web encyclopedia on food known as PracticallyEdible.com says that the word has been in use as early as the 1930's, though is rarely used.
Apparently, Turophile is also the name of a rock alternative band from Toledo Ohio, curiosly enough. Check out their organized noise on MySpace and Facebook. Their record label: Wisconsin's Finest.
