They eat their feelings in Germany, too, huh? I get it. In my lifetime, I've had grief ice cream, grief peanut butter and even grief boxes of Cap'n Crunch.
What food/eating concept would you like to find a single word for? Here's one: the act of going to the kitchen, looking for something to eat even though you're not really hungry, finding nothing that appeals, leaving the kitchen, and then returning to the kitchen just a few minutes later to start the process all over again. Does any language have a word for that?
