Better than English
Better than English is a fun site that collects non-English words that are of great use for describing a concept.
My favorite in what’s out there so far is the first: Drachenfutter, a German word that translates literally as “dragon’s food.” The website says “Drachenfutter are gifts that a husband brings to his wife after pissing her off. It is usually an attempt to avoid her wrath by giving her chocolate, flowers or other small gifts.”
If you have an example of a non-English word that sums up a concept, feel free to submit it.
