It is the kind of joke you hear on TV or in movies all the time. A character who speaks another language tries to translate a "beautiful saying" from his native language into English, but are unable to convey the real meaning (and hilarity ensues). Over at BraveNewTraveler, there is a really fun article
featuring 20 "Awesomely Untranslatable Words from Around the World".
Some of our favorites:
Japanese - "A mother who relentlessly pushes her children toward academic achievement"
German - Translated literally, this word means "gate-closing panic," but its contextual meaning refers to "the fear of diminishing opportunities as one ages."
And one that all travelers understand:
French - The feeling that comes from not being in one's home country.
