'Femmer' - a Geordie word meaning 'of questionable quality', picked up from my dad who, being Peterborian, himself picked it up when living/working on Tyneside.
'Haway' - Geordie again, used in conjunction with 'then' to mean 'come on then'.
'Nurk' - not sure of origins.
'Stiffen the crows' - an imprecation uttered by my father on more than one occasion.
