I've had a deep admiration for rhyming slang ever since I learnt what the seemingly innocuous insult berk meant. I used to feel quite irate about inauthentic examples, but since it's Christmas I'm sufficiently full of charitable spirit to ask: what newly-minted but properly-amusing examples are there?

If you don't know of any, I guess you can make up your own, we won't be able to pick you up on it, will we?
