Jimmy Riddle

Cockney rhyming slang. The term is mentioned in Partridge’s A Dictionary of Slang and Unconventional English, 1937, where it is listed as being ‘late 19th century’. Many rhyming slang terms that refer to names derive from real people – the celebrities of their day. A recent (1980s) example is a ‘desmond’ (a second-class degree – a 2:2, derived from Desmond Tutu). From the late 19th century we have ‘on your tod’, which refers to the American jockey ‘Tod’ (James) Sloan.

It’s unlikely that Jimmy Riddle was a real person. If he was, it would be surprising if he was well enough known to have had a phrase coined in his honour but for any records of his existence to be now missing. Several ‘Jimmy’ phrases were coined in the 19th century; for example,

– Jimmy Grant (immigrant/emigrant)
– Jimmy Ducks – a sailor in charge of livestock onboard ship. This is a similar coinage to that of a character working in the prison kitchens in the BBC comedy Porridge – ‘Luke Warm’.
– Jimmy Woods – someone who drinks alone.
– Jimmy O’Goblin – a sovereign.

These use the name Jimmy as a generic man’s name – much as Londoners and others now use John, and that’s probably how ‘Jimmy Riddle’ derived too.
