I think I should have elaborated more....

Uxbridge English Dictionary is a game played on the BBC radio 4 programme 'I'm Sorry I Haven't A Clue' whereby the panelists give new, humorous definitions to existing words. The game is introduced by the chairman who defines two similar sounding or similar meaning words, and give the real definition of the first, and a humorous new definition to the second. Thus my example - for non UK readers the humour is a satire based upon an MP who got into trouble for calling a policeman a pleb.
