Just happened across a site about Jewsmas:
In a well-meaning but misguided attempt to be "inclusive", Christian society has cast Chanukah in the role of the "Jewish Christmas". To liberate our ancient holiday from this false role, we introduce a new holiday, the true Jewish Christmas, Jewsmas. Now leave Chanukah the hell alone!
My impression is that Chanukah's transformation into "Jewish Christmas" has come as much from Jewish parents whose kids are jealous of Christmas presents as from direct pressure from Christian society per se (which the site also suggests on its Story of Jewsmas page), but I could be wrong; anyway, regardless, it's an entertaining site.
I particularly like the Jewsmas Traditions page, featuring a dreidel drinking game, the Refusal of the Ham ("rather than eat the ham directly, as the Christians would, the celebrant first cuts a slice of the ham and sets it aside, symbolizing the way our forefathers would have turned away the ham, for it is not kosher"), the Mumbling of the Carols, and the Ogling of the Shiksa.
Traditional Jewsmas recipes include cheese fondue. "Rabbi Akiba suggests that the bread symbolizes the corporeal nature of humanity, while the cheese [represents] the gooey goodness of the soul."
Jewsmas is celebrated on the first Saturday after Christmas--which, if my calculations are correct, is today. So happy Jewsmas!
