Vegetables don't get much of a look in, in the erotic context. There are some odd references to potatoes. Imagine dancing all night long and waist high in buttery potatoes. Vegetables are seemingly neutral when it comes to song writing. I better not speculate about the cabbage in Muscovite song contests.
Onions also have a limited life span in the romantic world.
Not going to be a big seller. Any correlation between these two foods and eroticism are now in short supply. True, meat names can be invoked to create cosiness or strength, e.g., my little lamb or my towering and perspiring bull. I hope that last reference to fish and tenderness did not upset anyone. These species don't seem to feature much in big time hits, although there have been a few songs devoted to shrimp boats.
