Christmas

Christmas is a holiday celebrated by humans on December 25, commemorating the birth of someone called "Christ." It seems to revolve around the exchange of material goods, the slaughter and festooning of conifers, and the consumption of roasted avians. Autobot intelligence suggests that at this time, humans gather together and don't shoot each other.
More importantly, Christmas is the focus 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.

Notes
- One Christmas season (somewhere between 1986-1992), Hasbro's Boys' Toys Marketing department internally passed out green-chromed Beachcomber and blue-chromed Seaspray toys as Christmas ornaments with a string attached to them. They were bagged with a card that read "Transformers Christmas ornament" on one side and "Merry Christmas from the Boys' Toys Marketing" on the other side.
