Stands for Canadian Biased Officiating. It is a term NHL fans may use if their team is playing one of the six Canadian teams and feel that the officiating is not fair. Usually manifests itself in terms of penalties called.

The penalties may be largely in favor of the Canadian team or may be evened out at the end when the American team has no hope of catching up. May also ivolve a Canadian penalty being immediately followed by an American penalty.

(n.)- Highly secretive Washington, DC dance club (referred to in public as the 'CBO' or 'Congressional Budget Office') located beneath the old supreme court chambers of the US Capitol. Constructed during the renovation of the Capitol building after its torching at British hands in the War of 1812, it hosts some of the hottest escorts y'all ever saw and has been the site of many political conflicts which have changed the course of American history. Most recent of these was Senator Harry Reid's (D-NV) crazy fucking chain fight beatdown of Representative Mike Pence (R-IN), an event credited with securing crucial votes for the passage of health care reform. Other historic events taking place there include: -John C. Calhoun's totally dickish keying of Abraham Lincoln's tricked out carriage, an act of aggression which elevated North-South tensions in the years before the Civil War -The lap dances received by anti-suffragist lawmakers, thus increasing their respect for women and changing their votes on the eve of a crucial vote on the 19th amendment -The awesome blowjob given by Sarah Palin to a senior McCain campaign adviser who, after multiple hits on the CBO's famous eight foot bong known affectionately as "The General Sherman," made the campaign-crippling decision to recommend her as John McCain's running mate in the 2008 presidential election.
Representative A (on phone): Hey you commie faggot, I'll show you where to shove your goddamn environmental regulations!
