Was about to place some uncommon (sometimes odd or funny) thangs here… maybe more “territorial” than “slang” but still not sure, though.
Well, no alphabet or other preferences / just to begin with…
There is all kinds of localisms in Canada. One of the most common is the ending of a sentence with eh? (pronounced hey?): it means the same thing as a brit or an oz saying "yeah?" at the end of theirs... do you agree with my statement, yeah?
Some of the most confusing ones come from Newfoundland and other points east in Canada, like “how's your feet an ears?” The meaning is “obvious”: it's friggin’ cold there too, so literally is anything at risk of freezing off at the moment. In a warm house meaning the same, "is everything good in your world?" while the rest of Canada uses something along the lines of "Howzit goin' eh?" This one confounds a bit: in Newfinese they say "where ya to?" and that apparently means "Where are you from?” (what town, are you a bayman or a townie?)...
