Christmas
Christmas is a holiday celebrated by humans on December 25th (or 24th, some places). It seems to revolve around the exchange of material goods, the slaughter and festooning of conifers, and the consumption of roasted avians. It may also be about the birth of a carpenter and/or purported global messianic figure, but despite the interaction between Transformers and humans, little data has been collected regarding this bizarre human custom.
