An ancient religion set up by Metalheads/Moshers/Rockers/Goths that has very fine layers that must be respected, can als be called the Sisterhood of Metal for female members, the layers/ranks are as follows:

The Brotherhood of Metal also has it's own army, that being

Judge of Metal (Not to be confused as a person who decides what Metal bands are good/bad, but a person who can issue a Mosh Pit Death sentence to a Chav scumbag
me: I'm a member of the Brotherhood of Metal.
