MegaChistmas is a holiday celebrated on the 25th of December, taking place of regular Christmas. Some celebrate the alternative, Festivus, as a response to the consumerist, greedy nature of MegaChristmas

Originally coined by a wrestler, many corporations liked the name and hopped onto the bandwagon of calling the 25th MegaChristmas.

VA-11 Hall-A and Stella's company both have Mega Christmas parties. Stella's birthday falls on this day.
