With six degrees, I separate MC's, from a business man that's good
From a nigga that was raised or just lived in the hood
From what a nigga says to what's understood

from Common – Dooinit Lyrics on Rap Genius

Common is referencing, not just the general idea that everyone on earth is connected to one another by no more than six mutual acquaintances, but the 1993 drama that launched Will Smith’s film career, based on a Pulitzer Prize-winning play of the same name. The film is about a black hustler and con artist who insinuates himself into the life of two guilty white liberals in New York.

Here, the meaning seems to be that Common can separate the gold from the dross in the rap world —– the fake gangsters from the true, and the real emcees from the con artists.
