So far the best explanation to the question has come from Sqad. However, is this a fictional assumption about Lilly Langtry, as is said about the story attributed to Sir Winston Churchill on the subject of 'breasts'. :-
//While being served a cold chicken lunch in America, Churchill asked the hostess: "May I have some breast?"
"Mr Churchill," she replied, "In this country we ask for white meat or dark meat."
The next day Churchill had an orchid delivered to her, along with the message: "I would be obliged if you would pin this on your white meat."//
