Norfolk has some interesting ones:-

mardle = to chat, have a bit of a natter
sorft = a bit daft or silly
mawther = a woman
dickie = donkey, as in "Ha yer father got a dickie?" , to which the reply is "Yis, an' he want a fule ter roid 'im. Will yew come?"

I particularly like bishiebarnaby for ladybird, and dodderman for snail.
I bet all these dialect words throughout the UK go back centuries, from original languages, eg Anglo Saxon, Norse, Gaelic etc. Isn't it fascinating?
