Jute

I used it in Scrabble once, thinking it was a made-up word and that I could get away with it.  My opponent challenged me on it and I, thinking quickly, retorted, “Jute … it’s a type of oriental flower.”

We promptly consulted the dictionary and found out, that indeed, it was a word but meant “the glossy fiber of either of two East Indian plants (Corchorus olitorius and C. capsularis) of the linden family used chiefly for sacking, burlap, and twine; also : a plant producing jute”

I was vindicated, and never let on that I thought I made the word up!
