An outlaw motorcycle club is a motorcycle subculture generally centered on the use of cruiser motorcycles, particularly Harley-Davidsons and choppers, and a set of ideals that purport to celebrate freedom, nonconformity to mainstream culture, and loyalty to the biker group. In the United States, such motorcycle clubs (MCs) are considered "outlaw" not necessarily because they engage in criminal activity, but because they are not sanctioned by the American Motorcyclist Association (AMA) and do not adhere to the AMA's rules. Instead, the clubs have their own set of bylaws reflecting the outlaw biker culture. The U.S. Department of Justice defines "outlaw motorcycle gangs" (OMG) as "organizations whose members use their motorcycle clubs as conduits for criminal enterprises". Organization and leadership While organizations may vary, the typical internal organization of a motorcycle club consists of a president, vice president, treasurer, secretary, road captain, and sergeant-at-arms (sometimes known as enforcer). In some clubs, localized groups of a single, large MC are called charters and the first chapter established for an MC is referred to as the mother charter. Sometimes the president of the mother chapter serves as the president of the entire MC, and sets club policy on a variety of issues, whereas other clubs either elect or appoint a National President for this role. Larger motorcycle clubs often acquire real estate for use as a clubhouse or private compound. Membership Some "biker" clubs employ a process whereby members must pass several stages such as "friend of the club", "hang-around", and "prospect", on their way to becoming full-patch (see explanation of 'patching' below) members. The actual stages and membership process can and often do vary widely from club to club. Often, an individual must pass a vote of the membership and swear some level of allegiance to the club. Some clubs have a unique club patch (cut or top rocker) adorned with the term MC that are worn on the rider's vest, known as a kutte. In these clubs, some amount of hazing may occur during the early stages (i.e. hang-around, prospecting) ranging from the mandatory performance of menial labor tasks for full patch members to sophomoric pranks, and, in rare cases with some outlaw motorcycle clubs, acts of violence. During this time, the prospect may wear the club name on the back of their vest, but not the full logo, though this practice may vary from club to club. To become a
