What Is A Mob?

Starting fresh, looking back at my Solar Mob Boss character, although I started to look briefly at influences for a mob boss as some kind of male gangster character, I feel as if this path is too generic. Looking into further research as to what a mob exactly is, it is a group of disorderly, and sometimes aggressive people. I don't think it necessarily has to be a mob boss who deals and sells drugs, I think this is too generic and so I decided to start fresh.
