Burger King: Subliminal Sex Messages?

The ad above is a picture of the BK Super Seven-Incher from Burger King that is served in Singapore. This ad was one of the most controversial ads around the world in the past few years. The crazy thing to me about this whole thing is the name of the sandwich...7 Incher??? So, when does sandwiches referencing to the size of a male's penis a good idea for products? If you didn't see or understand the reference of the sandwich to a penis, read the caption at the bottom of the ad. If the caption is too small for you, here is the caption:
"Fill your desire for something long, juicy and flame-grilled with the NEW BK SUPER SEVEN INCHER. Yearn for more after you taste the mind-blowing burger that comes with a single beef patty, topped with American cheese, crispy onions and the A1 Thick and Hearty Steak Sauce."
In the caption, there were many sexual references to pleasure and ecstasy through describing the sandwich. "Fill your desire with something long" is describing the sandwich, but in a way that you understand the size of it similar to a male's penis. "Yearn for more" gives off the satisfaction and climax feel of sexual intercourse through describing your taste buds going through the same motions.
