I live in Lancaster, SC but natives call it "Lank-uh-stir"
I grew up in SC but my mom's side of family was from Liverpool, so the dialect I heard at home was quite different from what I heard at school, and some things I heard never made any sense to me.
When my British grandmother first moved to the US, she and her Kershaw native husband went to visit his family, and the mother-in-law served breakfast. My grandmother asked what they were having & was told "eggzin branes".... she realized afterward that she had eaten eggs and brains.
some people say "mirrow" instead of mirror...
sometimes a bra a "briar" , and a chimney is a "chimley"
a friend of mine recently told me about a cartoon called "Rocky & Bo-Winkle"
... when I was about 11 or 12 years old I was wrapping xmas gifts & my SC native grandmother walked into the room and asked me "how much more d'you like?" ... I kept asking her over and over what she was saying, and she finally pointed to to the pile of gifts and I realized she was asking me how many gifts I had left to wrap before I was finished ("how much more d'you lack?"). It was kind of a weird failure to communicate.
