### Instruction: What are some examples of cockney rhyming slang?
### Response: Cockney rhyming slang is a tradition of substituting a word with a phrase that rhymes with the original word. Often the last part of the phrase is omitted making the slang even more opaque to outsiders. The practice is also common in Australia and other cultures influenced by the British. Common examples include "Use your loaf" meaning "Use your head" via the rhyme "loaf of bread" for "head", "Stop telling porkies" meaning "Stop telling lies" via "pork pies" for "lies", or "Who's turn is it to buy the Britneys?" with "Britneys" meaning "beers" via "Britney Spears".
