"Chocolate"
There's a reason that chocolate is nearly synonymous with Valentine's day. Many of the chemicals inside chocolate are known to give the feeling of love, hence, upon eating chocolate, one would feel love. It's a romantic image, chocolate in colorful heart boxes, handed to a loved one on Valentine's day, chocolate roses, chocolate everywhere.
I think it's only Spencer Reid that could possibly equate that same phenomenon to peas.
