Word, Y'all

While looking at the website Neatorama (specifically, the little blurb about the Pillow Fight League in Toronto) . . . .

. . . a random word popped into my brain, and now it's our word of the day: oubliette. An oubliette is "a dungeon with an opening only at the top" and it comes the French word oublier meaning "to forget" (i.e., it's a place where you can be forgotten, not where you can go to, say, forget about your troubles, though I can see how that could work -- I wouldn't be worried about car repairs or taxes if I happened to be thrown into an oubliette). Live it, love it, learn it. See if you can use it in casual conversation.
