In Wales, people romanticise the word cwtch as though it’s the greatest word in any language ever to have existed (it means cuddle).
In Bristol, some people say “Blige!” instead of blimey, or something like that.
In Glasgow they apparently say “There yer dinner you absolute cunt” I have heard.
In Scotland, they say “excited for” instead of “excited about” which is obviously the grammatically correct way.
What colloquialisms does your shithole corner of the country have?
