I once used the word "quine" in Scrabble. We had a house rule that allowed all English words on English Wiktionary if you could give a more or less correct definition. I gave the computer science definition but it turns out it had a more interesting meaning that immediately caught on in that particular friend group: "To deny the existence or significance of something obviously real or important".

"Quone" is another good Scrabble word, though it's usually only found in medical dictionaries.
