There are no statistics on the least common tattoos. The most common tattoos are barbed wire on the upper arm, a rose and the name of children of loved ones.
Barbed wire, also known as barb wire less often, bob wire (or, in the southeastern United States, bobbed wire), is a type of steel fencing wire constructed with sharp edges or points arranged at intervals along the strand(s). It is used to construct inexpensive fences and is used atop walls surrounding secured property. It is also a major feature of the fortifications in trench warfare (as a wire obstacle).
A person or animal trying to pass through or over barbed wire will suffer discomfort and possibly injury. Barbed wire fencing requires only fence posts, wire, and fixing devices such as staples. It is simple to construct and quick to erect, even by an unskilled person.
Tattoos are commonly used among criminals to show gang membership and record the wearer's personal history—such as his or her skills, specialties, accomplishments and convictions. They are also used as a means of personal expression. Certain designs have developed recognized coded meanings. The code systems can be quite complex and because of the nature of what they encode, the tattoo designs are not widely recognized.
Russian criminal tattoos have a complex system of symbols which can give quite detailed information about the wearer. Not only do the symbols carry meaning but the area of the body on which they are placed may be meaningful too. The initiation tattoo of a new gang member is usually placed on the chest and may incorporate a rose. A rose on the chest is also used within the Russian Mafia. Wearing false or unearned tattoos is punishable in the criminal underworld, usually by removal of the tattoo, followed by beatings and sometimes rape. Tattoos can be removed (voluntarily, in the case of loss of rank, new affiliation, "life style" change, etc.) by bandaging magnesium powder onto the surface of the skin, which dissolves the skin bearing the marks with painful caustic burns. This powder is gained by filing "light alloy" e.g. lawnmower casing, and is a jailhouse commodity. Irezumi
The human body is the entire structure of a human organism and comprises a head, neck, torso, two arms and two legs. By the time the human reaches adulthood, the body consists of close to 100 trillion cells, the basic unit of life. These cells are organised biologically to eventually form the whole body.
