From Rap Dictionary
The God Body Nation (or God Body / GB / GBN / TGB / TGBN for short) is a large fluidly connected international black organization. This organization is a unity of smaller individual sub-groups known as Ciphers. Each cipher is known to have their own distinctive name, but all use the number "7" hand sign when saluting one another. God Body also has another hand sign they throw up which resembles the peace sign, but with both fingers together.
