Some slang from York, UK that was common in my childhood:

Pushknacker - a bicycle, particularly a street bike. Best one on this list, tbh, it’s a great word.

Lagin - pronounced la-jin. Means rubbish. Like, “your pushknacker is lagin!”

Weeny - really, as in “that’s weeny lagin”

Chava - pronounced char-va, a derogatory term, to be honest I never had any idea what the actual meaning was but it’s an insult, as in “ya fuckin chava!”. I was confused when the word “chav” suddenly became a thing years later and I’ve always wondered if they are related or if it’s a coincidence.

Ding - what people would now call a chav, also used ad a general insult.

Dingraff - either the full for of ding, or an extension of it, no idea. General insult.
