It seems to revolve around the exchange of material goods, the slaughter and festooning of conifers, and the consumption of roasted avians. More importantly, it is the locus of a powerful "spirit" manifesting in charity, goodwill, and appreciation. Even hardened Decepticon warriors and vengeance-driven humans are subject to its influence.
Some Autobots have been known to don a red outfit with a bushy, white beard as part of the Christmas ritual. While not the most extreme example of quasi-fetishistic anthropomorphization among Transformers, this case is notable in its lack of explanation. Perhaps it is related to the similarly-opaque "Christ" figure at the center of the holiday.
Another human custom, Black Friday, is rumored to be the busiest day of shopping for the material goods needed for exchange on Christmas.
