I too grew up with Finnish phrases that I never understood lol but what I do understand is ALWAYS SISU“You can go broke on good deals” and random Finnish phrases like istu istu “sit down, sit down”
When referring to a very small increment of measurement, my Gramps used to call it "a **** hair" hahaha it's especially funny when you realize that this is the best man I had ever known and would never cuss other than this.
And the classic: "I haven't seen you since you were yay-high to a grasshopper"
Ditto,When I was in 4th grade I fell on my right knee while jumping rocks on a rock pile. A few days later there I am with my knee the size of a grapefruit and can't even bend it, and he comes in and yells at me for not getting outside to help him with the work. He says "rub some dirt on it and you'll be fine.......now get out there and give me a hand".
A few days later I'm in the hospital getting treated for a major staph infection. Oh the love....LOL. Pretty sure his demeanor wore off on me. Probably why I never became a doctor......I'm pretty much like Dr. House on TV.
Not sure if it's considered metric or imperial but I've heard the same measurements used, only smaller measurement is "a half a **** hair!"
