This one came up at a friendly gathering I was at last week. My best friend and his wonderful new bride have found a Yorkism that separates them, and I thought I'd help settle their disagreement with a lovely poll.
My answer to come in a future post!

Ah, but in the hard coal region of northeastern Pennsylvania, you don't rinss it or rinzz it, you rench it.
