A party or get-together of any kind up here in MN is a "doings". "Theres a doings at Les' this weekend." implies that there will be fried fish, lots of beer, and a bonfire.
they say "by-dee-by" as well which means "by the way" and I will never say it no matter how long I live here because it sounds stupid.
When I think of more I will add them...the day is young there are lots of Minnesotans to speak to before its over!
when i first heard you mention tank...around here, when you're tanked, you're DRUNK.
a hot dish was a good looking girl/lady, i think this is from the old movies.
goulash, is cooked noodles, with tomato sauce, hamburger and lots of mozzerella cheese on top...yum, yum!
