In Britain, England specifically, there is a dialect called 'Cockney Rhyming Slang'. It is a dialect that is very local and foreigners find it hard to understand. Cockney Rhyming Slang phrases are derived from taking an expression which rhymes with a word and then using that expression instead of the word. For example the word "look" rhymes with "butcher's hook". It is hard to get your head around but if you do some research on it you will find it is quite a funny dialect!
