The feeling you get when someone near you is eating a gross combination of food and/or sauces.
Person 1: Do you see that kid over there? What is he eating?
Person 2: Oh that's Person 3, he eats the grossest combinations of food I've ever seen. Looks like today he brought a ham sandwich with ranch dressing and bar-b-que sauce and he's dipping it in his milk and his soup. Gross.
Person 1: That causes me to have a lot of Culinary Discomfort. I wish he would just stop.
