In my younger years, I had Big Mac Attacks. Is that close?
Nope, Festivus is a made-up holiday from "Seinfeld":
According to Seinfeld, Festivus is celebrated each year on December 23, but many people celebrate it other times, often in early December. Its slogan is "A Festivus for the rest of us!!" An aluminium pole is generally used in lieu of a Christmas tree or other holiday decoration, shedding holiday materialism. Those attending participate in the "Airing of Grievances" in which each person tells each and everyone else all the ways they've disappointed him/her over the past year, and after a Festivus dinner, The "Feats of Strength" are performed. Traditionally, Festivus is not over until the head of the household is wrestled to the floor and pinned.
