Noun. From German.
“The weight that is gained from emotional overeating.”
Kummerspeck can be literally translated in this case, but it comes out as grief bacon, and aside from conjuring up images of a piece of back bacon with a veil, there’s not really much else that can be derived from that translation.
And yes, I know the woman in the stock photo above isn’t really demonstrating kummerspeck, but the humour when it comes to her trying to have a proper meal with friends must be hilarious.
