Black Mob :
black mob is more popular, to shanka mob, they is considered fruity, but black mob has a very much larger crew than shanka mob, for the reasons that shanka mob is hard to get into.
Shanka Mob :
shanka mob is less popular, but more ghetto. They is all 100% hood and is always together in their crew.
To black mob, shanka mob is considered wanna-bes for the fact that there is so much less people in it than black mob.
The cool thing about black mob and shanka mob is they are also a crew all together in one, very confusin', but so crunk.
