To me, it kind of sounds like a bastardized version of “English (UK)” with a Boston accent attached to it plus bizarre slang and strange spelling of some words (I.e. gaol is pronounced as “jail” I know, WTF? As I’ve thought they’re trying to spell goal).
The weirdest part are the different meanings of words that are spelled the same (I.e. “Thong” is defined as a swimsuit underwear in American English but from English AU, it’s flip flops) along with “C*NT” being part of their vernacular.
it sounds like an Australian accent. there are tons of accents that have their own history and context. it’s shitty to call them weird, bizarre, or bastardized and makes you seem narrowminded.
