I suggest you go back to the question-page and scroll down to the one seven below your own. The first response there refers to the opinion of Michael Quinion as to the word's origin. He, by the way, is a noted etymologist and lexicographer...ie an expert on the history and development of English words and phrases. Nowhere does he imply that the word is from Geordie-land; indeed, he rather suggests it may be of south-east provenance. Sorry...but there you go.
