Milwaukee nikkas always seemed liked a more laid back playa/hustla version of Chicago nikkas.
Also, ppl be talkin bout Chi-town nikkas havin southern sounding accents, when I would never mistake a black Chicago accent for a southern one, but Milwaukee nikkas...........lol.......I could easily mistake they accent for one of them inland upper south Louisville/Nashville type accents. Might have something to do with the extreme segregation in the city like others have mentioned.
