Noun: An extra piece of food that you cook with no intention of
consumption for the current meal, but with
knowledge of the fact that you will be hungry again shortly after. (Also applicable to
intentionally ordering extra food at a restaurant in order to fulfill the same purpose)
Jack: Why are you cooking four
hamburgers for dinner John? I told you that Kim couldn't come and it would just be
the three of us for dinner!
John: Dude relax, I'm just making some
auxiliary food! You know I'm gonna be hungry again later.
