A common phrase people from the Boston area say when they think something is super awesome.
It is traditionally pronounced in a Boston accent, where the R traditionally makes an AH sound:
Joe: The sox won...again!
Bob: Wicked Hardcore!
Adj: A New England (specifically Massachusettes)slang term for something that is extreme or incomparable in nature or in quality; cool; awesome
A true Bostonian may remark:
We were all at the Aerosmith concert last Saturday night.
It was wicked hardcore!
