The Super Bowl is the National Football League’s championship game. “Superbowlian” (or “Super Bowlian”)—the adjective—reflects things about or like the Super Bowl; the noun term could mean the Super Bowl’s players or fans. Anything called “Superbowlian” (also lowercase “superbowlian”) is likely to be big, like the Super Bowl itself.
 
“While advertisers ‘pulled back on the usual Superbowlian extravagance this year’” was cited in February 2002. “Super Bowlians” (referring to Super Bowl fans) was cited in November 2002. “It was a positively Super Bowlian moment” was cited in January 2003.
