Being brought up in the Midlands near Coventry/Birmingham, by a family of Scots and Cumbrians (Carlisle) my language was a cause for hilarity - at school the odd words used for things in the family drew blank looks, and vice versa when I returned home!
Odd things from home:
"Mythering" was whining;
Searching through boxes/cupboards was termed "ratching" (or wratching? I never saw it written !);
"Whist!" - not the game, but a northern term meaning "Do be quiet!";
"Jai" (pronounced to rhyme with "my") - meaning crooked or unbalanced. (We think this word was "invented" by an aunt as no-one else in the family ever heard of or used the term!);
On the subject of funny sayings: whenever anyone commented on how hard the rain was coming down, my father would respond "Well, I'll sign the pledge when I see it going up!" - this, from a man who was practically tee-total!
