Branding

This is a means of permanently marking or scarring the skin by burning it with hot metal.  This was used historically as a means of identifying people's slaves and, of course, cattle. Although some people find the slavery connection offensive many African Americans are reclaiming this method of body modification by choosing brands that identify them as members of a gang or brotherhood. They have also risen in prominance in college fraternities. In the UK branding is still a legal grey area and there are no legitimate ways to get a brand other than by doing it yourself. It is available on the UK underground scene and may become more widely available in the future if the authorities are prepared to consider it as a legitimate form of artistic expression.

If you want a brand or just want to know more definitely do plenty of research before you try anything. Be very careful how you go about getting it done. Make sure you and the brander (if there is one) really know what you are doing.
