JACK PUDDING is not a desert. The 18th century definition is "A buffoon". So the next time you get mad at someone, which I hope doesn't happen too often, call them a Jack Pudding. I bet you will both forget what the argument was about.
IRON RUFFLES are not a fashion statement. The 18th century definition is "Handcuffs". Iron ruffles sounds so much better if that is possible.
JACULATE is a variant spelling for chocolate. For some reason jaculate just doesn't conjure up something sweet in my mind. I suggest you don't use jaculate on Valentine's Day. You might not get the response you thought you would.
