How to Speak M'Wacky
Slanguage has some fun (if somewhat inaccurate and incomplete) lists of various regional US dialects. The closest they get to where I live in Wisconsin is Milwaukee and Minneapolis. Minnesota is essentially a foreign country as far as us Wisconsinites are concerned, so it doesn't really count, but the list for Milwaukee is pretty close to what you'll hear around my neck o' the Northwoods, just add the following:
Them are (those are): as in "Them are nice shoes."
Borrow me (lend me): as in "Borrow me them shoes, wouldja?"
Doncha know (obligatory ending of any rhetorical question): as in "Them are nice shoes, doncha know."
Stop-and-go light (traffic signal), as in "I was in such a hurry to buy a pair of them nice shoes that I ran the stop-and-go light!"
Jeez o' Pete! (Jesus and Peter): Catholic exclamation of surprise/exasperation as in "Jeez o' Pete, I ran the frickin' stop-and-go light!"
