According to the Reader's Digest, I have kummerspeck. It's the German word for "excess weight gained from emotional overeating. Literally, grief bacon."
Someone who attends funerals just for the food is a pesamenteiro (Portuguese). Well, at least I'm not one of those... yet.
As for my grief bacon, I will try to do better by zeg. (Georgian: "the day after tomorrow.")
