While you ponder what that might be a euphemism for, I'll just tell you that in actual fact tennis player Novak Djokovic has purchased the entire 2013 supply of cheese made from donkey milk. Only £800 per kilo.
Wimbledon winner and world No 1 Novak, 25, wants the donkey's milk cheese to supply a new chain of restaurants in his Serbian homeland. The delicacy, known as pule, is made in Zasavica, Serbia, and is described as similar to Spanish manchego. Donkey milk is said to be very healthy for humans as it has anti-allergen properties and is low fat.
