Big Butter & Egg Man, Banana in Your Fruit Basket, Grinding Mill and other carnal songs

"I want a butter and egg man. Won't some great big butter and egg man want me?"Why does this woman sing so emphatically about wanting a man who possesses BIG BUTTER and EGGS? Is she headed down a dangerous dairy path? With all that is known in 2013 about a diet high in cholesterol, this song might already be maiming young minds but could the butter and eggs be representative of something more than food? Is this a tongue-in-cheek metaphor?
