Originally founded in 2016, the BOIS are a group a highly intelligent, motivated, steal your girl operators. They are an international response team coming to the aid of all fellow BOIS. Most of the members of the BOIS are based out of Clayton, North Carolina. In order to become a member of the BOIS you must be hung as fuck, extremely good looking, rowdy, and you must be able to uphold a standard of dankness. The female counter part of the BOIS are the GOIS who have different but just as challenging requirements to be a member of.
