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 one percenter 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.\n\nWhat does mc mean on a biker vest? OK. Let's think. My stream of consciousness:
