Ugly Christmas sweaters

One term I keep hearing this December is "ugly Christmas sweaters". As far as I can remember someone, usually female, has shown up at work or at a holiday party wearing one of those things. Now, I have been told,  they are suddenly hip. In the Macon Georgia Baptist Woman's League they have Ugly Christmas Sweater parties. Do they  really have them in artsy hangouts in Brooklyn? Personally I think that if you came to an actual  hipster party wearing one of those you would be scorned upon. Probably they were hip last year but not now.

I wish I had an ugly Christmas sweater. Socks I have, ties I have, but not
sweaters.

Editor's note: I finally have an ugly Christmas sweater, well at least an ugly Christmas vest. There is a nice piece on the genre on Slate. 12/12/14
