Just a few I can think of off the top of my head.
When the boys were little and we were out I'd say "give me yer donny" and at home they would hear "wash yer donnies". Confused? Donnies are your hands. Dunno why

My Dad used to take his snap to work. That was his dinner. Quite often a piece of jam (a jam sandwich) and some cake.
If we take a long time to get somewhere or even to do something we might say that we've "been all 'round the Wrekin" in the process. The Wrekin is a hill on the ourskirts of Telford.
