This sneaky invention involves a small group of participants within a larger meeting. The miscreants agree to slip in an unexpected word without raising suspicions. A points system can be used, or even a league table.
We hear of a cabal agreeing over lunch to focus on Italian food in the afternoon session. And so it was that the chair - who was in on it - summed up with the cunning analysis: "This is obviously a complex problem. It's like a spaghetti junction . . ."
She followed up: "That's a knocky (gnocchi) issue we should take time to consider."
They don't have to be in the dictionary and the ruder the word, the more points. Good luck.
