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.
La befana. Supposedly she was a woman who was offered to go see jesus when he was born hut was too busy, and has spent all eternity making up for it since by handing out presents and candy and sweeping people's floors.
