As defined by Urban Dictionary, Cashmas (also know as $mas) is the:
primary holiday celebrated in capitalist cultures. Generally observed around the winter solstice, Cashmas is a celebration of materialism in which its celebrants attempt to flatter or impress relatives, friends, and acquaintances with the extent of their purchasing power (the "power to get"). Cashmas co-opts signs, symbols, and sympathies from other religious holidays of the winter season to mask its foundation of conspicuous consumption.
