I'm the most Kkkrackkkers of Amerikkkans so my tradition is just getting drunk off mulled wine and re-watching bad holiday movies with relatives I only kinda like.
I'm sometimes a little jealous of people who have weirder shit going on, like gremlins who slam doors and steal sausages or shitting Christmas logs. We need to bring back weird ass half-pagan shit.
Hmm, nothing too weird... my ethnic culture technically recognizes the Christmas season at the start of September, and in those last 9 days before Christmas, we have a novena, essentially a series of masses that lasts 9 days...
Oh and we also eat rice cakes w/ margarine...
