I don’t know that I have ever used the word “wicked” in a sentence unless I was describing a character from the Wizard of Oz to someone who had never seen it. But that has probably never happened since I rarely converse with anyone from outside our galaxy.
The first thing that came to mind when I read the prompt was a film I saw in the early 80’s based on a great Ray Bradbury novel, “Something Wicked This Way Comes.” It was not nearly as good as the book, but movies seldom are. It was interesting enough to hold my attention and be wary of carnival people, which I still am.
If I were from Boston, I would have used the word thousands of times as in “that chowda was wicked good” or “that sunset was wicked pissah”. But sadly. I live in the Deep South and have had no reason to use the term “wicked.”
If I were a sportscaster I would have used it as in “strike three on a wicked splitter.” If I were a Boston sportscaster I could say, “that was a wicked good slider from Schilling, wicked pissah that it was hit for a home run.” (see, I hate the Red Sox. They are truly wicked.)
I googled the word “wicked” and the first hundred or so entries referred to a Broadway Musical about the “untold story of the Witches of Oz.” I could sit in the Orchestra for $110.00 a ticket. That is “wicked expensive” considering I have no interest in learning more about those witches and sitting that close there is always a chance of a house falling on me or getting strafed by a stray shingle. But I could sit in the Rear Mezzanine for $50.00 a seat. That sounds like a “wicked” good deal and appears much safer.
