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.
Bowl of cheezles that one of your cousins stuck their fingers in, licked them, and then put back in the bowl. That you end up eating anyway by the end of the day
That cousin is 29 now, I swear he still probably does it. Its tradition after all
