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. In the United States, where the holiday is most actively observed, Cashmas traditionally begins on "Black Friday", that is, the day following Thanksgiving Thursday in November. Holiday observations traditionally end on January 2nd, but may arguably be said to extend through "Super Bowl Sunday" of professional American football. This event can occur as late as the month of February.

Also "$mas".

A phrase popular among first year Latin students, the phrase means "always wear underwear." The literal translation is "always where under where."
