My niggas follow a code of ethics with loaded weapons
Watch your tone when we're speaking, don't even show aggression

Meaning

Gangs and mob members have always acted by a certain set of guidelines since their beginning. Each group operates under a different set of rules and major consequences come from not abiding by them.

An famous example of this, was the Aryan Brotherhood refused to protect Charles Manson went he went to prison, because he was tried for committing crimes against children, which goes against their bylaws.

Members have been known to not show any signs of anger if they’re agitated, so watching how you interact with one could be to your benefit.
