A motorcycle club is a group of individuals whose primary interest and activities involve motorcycles. Motorcycle clubs vary a great deal in their objectives and organizations. Mainstream motorcycle clubs or associations typically have elected officers and directors, annual dues, and a regular publication. They may also sponsor annual or more frequent "rallies" where members can socialize or specific sports events. The abbreviations MC and MCC are both used to mean "motorcycle club" but have a special social meaning from the point of view of the outlaw or one percenter motorcycling subculture. MC is generally reserved for those clubs that are mutually recognized by other MC or outlaw motorcycle clubs. This is indicated by a motorcyclist wearing an MC patch, or a three piece patch called colors, on the back of their jacket or riding vest. Outlaw or 1%er can mean merely that the club is not chartered under the auspices of the American Motorcyclist Association, implying a radical rejection of authority and embracing of the "biker" lifestyle as defined and popularized since the 1950s and represented by such media as Easyriders magazine, the work of painter David Mann and others. In many contexts the terms overlap with the usual meaning of "outlaw" because some of these clubs, or some of their members, are recognized by law enforcement agencies as taking part in organized crime.
