The little book of cockney rhyming slang - E. M. Kirkpatrick

Starting out as a private language to fool coppers (grasshoppers) and
their narks (Noah's Arks), Cockney rhyming slang has always had a
tremendous vitality. So don't be daffydowndilly - take a butcher's at
this little Captain Cook. What's more, if you're feeling a bit boracic,
it isn't going to break the old iron tank, or empty out your Lucy
Lockets. Hundreds of definitions, for not a lot of sausage an'mash -
just the thing to amaze your chinas over a pig's ear down at the
rub-a-dub.
