Only ever heard it from people with a speech impediment and I've lived in Sunderland for 52 years. You might have taties in your lugs
I’ve heard various versions of the mispronunciation of words with an ‘r’ in it. There is an element of truth to this. But, and this is far, far more prevalent than the observation of the spoken word discussion. There are three posters on this thread who don’t really give a fuck about the pronunciation. The motive is to wind up attack and those who disagree and it’s a perfect topic to stir up such antagonism to allow this to happen.
