Uncle Fester - Child Molestor

Not originally used by the gentry of old east London town, now officially part of the Cockney rhyming dictionary and appearing on various 'Cockney' translation sites, ''Uncle Fester'' has become the new ''Nonce'' or ''Kiddie Fiddler.''

Apparently movies such as Lock, Stock and Two Smoking Barrels - full of faux Cockney wording - encouraged people to take up creating their own rhyming slang.

''Uncle Fester'' has been affectionately adopted and accepted as a more modern alternative to ''nonce'' in many areas of East and South London.
