A Word we Need

From Futility Closet;

Mamihlapinatapais, from the Yaghan language of Tierra del Fuego, is considered the world's most succinct word — and the hardest to translate.

It means "a look shared by two people, each wishing that the other will initiate something that both desire but that neither one wants to start."

You might laugh at sheer nuance of the word, but it happens.

That's why we need a word for it in English. That way, when it happens we can mention the word, and we'd both laugh, and everything would be okay.
