southeast WI here -sheboygan to be specific. here are some off the top of my head.
brats -pronounced "brots" -
speaking of brats we ordered one in germany at Epcot once and it came with saurrkraut and we took it off and ate the brat with ketchup & mustard, and ate the saurkraut plain with a fork

.
ice melt is called " salt"
soda - white soda for 7-up,etc. orange soda, rootbeer,etc.( and pepsi and coke are NOT the same - i had an "disscussion" with a carnival worker this past summer - he assured me that $3.00 soda was coke - he almost wore it.


)
we have an accent - even a county wide one

we sound different from others in the state ( not sure why)
we call and outdoor cooking "frying" - "do you want to come over for a brat fry" or " going to fry some burgers"
anything BBQ has sauce on it - BBQ'd ribs. BBQ'd chicken.
beer batter - on onion rings/fish/etc -no panko or bread crumbs yuck
we dont call the beach "the beach" we say " were going down to the lake"
