We take things like that for granted if we grew up with them. I just wonder how much variations of English have blended thanks to TV etc. Kids here will use US and Australian terms all the time now.
Here in Bedfordshire, UK you may hear people add 'right' to the end of sentences like the Canadian 'eh'. They will also talk about 'old boys', but that can be someone of any age. There's an old guy (actually old) who empties the litter bins and he always says 'Alright me old mate?' to me even though I don't really know him.
Of course US and UK English have lots of differences.
That is a good one. I think there were some instances while I was watching Ted Lasso and The Gentleman where they were using that term "right" that you were talking about. I feel like there was another one too, but I can't remember it now.
I remembered the other one that I heard in those shows and I found it fascinating. "Innit" or however you spell it. I'm guessing it's a slang form of "isn't it", but it seems to be used more as a regional thing maybe.
