Xmas (also known as Xtreme-More) is a holiday celebrated in Burgburg and Eurump. Secular movements have risen to rename the holiday Christmas, because they believe the X to be too frightening and violent to those who do not house faith in Slam. Xmas celebrates consumerism and general greed, but because of how honest it is about being terrible, most people do not fret over the immorality of the holiday, and take it as a good excuse to be XTREME with friends and family. Upon the discovery of Heck, the holiday was more widely accepted, as practitioners could now use the excuse that they were punishing halfhearted sinners to cover up their selfish desires.

It is no longer a recognized holiday in Finland after various government reforms to become a more hostile country.
