There's an East Coast bias in coverage of jackass baseball fans. Red Sox and Yankees fans get all the attention for being loudmouthed narrow-minded louts, but there's a particularly virulent breed of fucktardation on Chicago's North Side that deserves more attention. Wrigley Field is the hub of Midwestern douchebaggery, pulling in the biggest douches in a five-state radius. The combination of lively bleachers, an active singles bar scene next to the stadium, and a high percentage of Northwestern graduates who work as consultants make Wrigleyville a veritable douchetopia. Or Xanadouche, if you prefer.
That said, this "catch the baseball with your beer cup then chug it" is a pretty cool routine. It very nearly ruined my rant against douchey Cubs fans.
