How long before we do thanksgiving? Can't we think of our own ideas?!
Thanksgiving was your idea (if you’re English, that is). It’s based on English church Thankgivings for a good harvest. The first people to observe it in the Americas were British.
I get irritated when my DC talks about his "pinky." Yurgh! It's a Little Finger FFS! Pinky sounds creepy.
As others have pointed out, Pinky/pinkie is a Scots word brought to North America by Scottish settlers.
Yes! Quite. Can you get it? I suppose you could, if you can vault the counter and grab it.
"Can I get" is grammatically correct and is also used in parts of Scotland. The only thing that one can quibble with grammatically in "can I get" is the use of "can" rather than "may." The definition of "get" is "to come to have or hold (something); receive". So "can I get" is as correct as "can I have." "Get" does not have some sort of built-in reflexive as so many posters on MN seem to think.
Supper makes my skin crawl, and it is distinctly British.
Supper is widely used in the US, especially in the South as another word for an informal dinner.
Also, a lot of the American words and spellings you see on MN are from actual Americans. There are quite a few of us on here.
