gets a bit ‘dodgy pubs’ territory, people genuinely call ashington ‘ashghanistan’, and i’ve heard someone call byker ‘bykhdad’ but they were blatantly the only person who has ever done that in the history of the world. have also heard people call the meadowell estate ‘meadohell’ and pottery bank ‘pottery stank’, both highly unoriginal.
i don’t do any nicknames or abbreviations religiously other than ‘shields’ for south shields, but literally everyone who has ever lived within 10 miles of it does that. occasionally join in with things like washy for washington, ashy for ashington, sun’lun for sunderland, th’bay for whitley bay.
