DIFFICULT TO UNDERSTAND?

I found this video in Youtube and it is about Cockney accent , especifically about Cockney rhyming slangs

This is what I understood and then ...¿¿¿¿¿¿¿??????

"A lot of people have asked if I can do a Cockney accent , so I'm keeping with a fake language theme and some of my videos I thought I do a cockney accent with some fake cockney rhyming slang ... "

The term Cockney refers to working-class inhabitants of London, particularly east London, and the slang used by these people. Here is an example of a Rhyming slang which consists of replacing words with short phrases which include a word which rhymes with the original one (and sometimes removing the rhyming part). For instance, the term "boat race" (or just "boat") might be used to refer to a person's "face", "plates of meat" (or just "plates") would mean "feet", and "bees and honey" (or just "bees") would mean "money".

The origins of rhyming slang are disputed. It remains a matter of speculation as to whether it was a linguistic accident or whether it was developed intentionally to confuse non-locals. If deliberate, it might have simply been used to maintain a sense of community; or to be used in the marketplace for vendors to talk amongst themselves without customers knowing what they were saying; or it may have been used by criminals to confuse the police and tax collectors.
