The Sun or possibly the News of the World came out with "They call him Wor Blackie" and just like when they said of Ginola "The man the Geordies call Frog on the Tyne" it wasn't anything I'd heard any Newcastle fan say and seemed to be just some "clever" thing london journalists had made up and put in our mouths.
Reminds me of another jounro "Wouldn't it be so funny if" presented as reality, with stories claiming whever Emma Watson answered a question in class other students wou;d shout out "Ten points to Gryffindor" to hysterical laughter, which unsurprisingly turned out to be entirely invented. Or the wresting where Michael Cole does this painfully contrived "The WWE Universe is calling him..." (insert nickname Vince McMahon came up with, copyrighted last week and wants the fans to call this guy.)
