Kat

I think its a yorkshire expression

It can be used as a term of address, usually affectionate. E.g."Right cock, that'll be 46 pence please. Would you like it in a bag?"

If I remember rightly Charlie Williams (British Comedian) used to call people "cock". one of the first black players in British football after the Second World War, and later became Britain's first well-known black stand-up comedian.

In fact, he broke all the rules about being PC.

He caused offence to some by defending the Robertson's golliwog trade mark, and for saying that immigrants to the UK should conform to the British way of life.

Makes you wonder doesn't it.
