Wicked good

I wonder how "wicked" got to be such a ubiquitous word in New England. Everything is wicked something. Wicked good, wicked bad, take a wicked left, etc. Sometimes something is just plain wicked. Take a wicked bag was the superlative for take a bag, which was about the worst insult you could say to somebody. I still say it, as does Mary. Even the big M knows and understands proper usage of wicked, but she doesn't say it.
