The fortnightly British satirical magazine Private Eye has long had a reputation for using euphemistic and irreverent substitute names and titles for people, groups and organisations and has coined a number of expressions to describe sex, drugs, alcohol and other aspects of human activity.
Over the years these names and expressions have become in-jokes, used frequently in the magazine without explanation.
Some have passed into general usage and can be found in other media and everyday conversation.
Towards the end of each issue, the magazine contains increasingly surreal jokes, references and parodies.
Many of these have evolved and are familiar to long-term readers.
