English and Scottish sayings/slang are my favorite. Southerns have some good sayings but they are not as enjoyable for me to hear, maybe because I used to them.
Indeed when I was growing up even though I was in a rural area people who lived on farms had a noticeably different accent from those of us who lived in coastal fishing villages even though the farms might only be a kilometer or so from the coast.
e.g.
“A ken a ken im, but a da ken far a ken im fae.”
or
"I know I know him, but I don't know where I know him from".
And of course, I was a "wee loonie" when I was younger.
Edit: Of course, the biggest crime I commit when it comes to class is, of course, using "toilet" rather than "loo".
On the other hand, I find it almost impossible to read text that is supposed to show Scottish accent, like the one from arethuza.
I've probably said something like that many times when I was younger (I now have, as someone described it, an "affected Edinburgh accent"). However, you can get silly Scots phrases like:
"Fit fit fits fit fit?"
Or, my favourite:
"Aye, ane an an ingin ane an a"
The latter I can't say without almost singing (and smiling).
