Explain meaning and usages of 썰렁 - 썰렁해 and/or 썰렁썰렁
To be clear, I have heard it used in each of these ways. I do not need an explanation of Noun, Noun+하다 (Noun+해), but if any usage carries a different meaning, please indicate the nuance.
I should say, that I understand it to be a comment about one's humor and perhaps also to have something to do with the cold. Perhaps it is a play on words.
I'm also interested in any negativity that this might convey in each particular usage.
