We have our own here in NE. Going back a bit in time “wicked” could be used in a couple of ways. Along with the standard meaning, it could also be used instead of “very”, as in “that pie is wicked good”, or “she’s a wicked bad driver”.
If I weren't dyslexic and ADD-ed, and if life were, like, 300 years long, I'd be a philologist. "Wicked" is in the NE, used as a superlative or intensive. Then "bad" comes into play, I think beginning in black English but spreading quickly, also as an intensive.
It's fascinating.
