Pop and Weasel?
These words are derived from Cockney Rhyming slang which originated in London. Cockneys were a close community and had a suspicion of strangers and a dislike of the Police (they still do!) Cockneys developed a language of their own based roughly on a rhyming slang - it was difficult for strangers to understand as invariably the second noun would always be dropped. Apples and Pears ( meaning stairs) would be abbreviated to just 'apples', for instance, "watch your step on the apples". To "Pop" is the slang word for "Pawn". Weasel is derived from "weasel and stoat" meaning coat. It was traditional for even poor people to own a suit, which they wore as their 'Sunday Best'. When times were hard they would pawn their suit, or coat, on a Monday and claim it back before Sunday. Hence the term " Pop goes the Weasel"
