Some of the crews listed such as Get Touched Boys are supposedly Rap cliques. There's another that interview with members/associates that explain the names; Be touched by their music hence Get Touched Boys, Nicknames from their projects/locations and others are just hustle theme names : Mo Money, All Bout Money, etc.

But man these crews creativity is eccentric !

@ Scorsese,
It's mainly focus on the crews and some have ties to the UBN or Crips. But your right about them not having SMM on the list.
