I'm fantastic, FURIOUS like the Five from B'lawn
Brooklyn phenom'

from Yasiin Bey – Next Universe Lyrics on Rap Genius

Meaning

Mos Def is fantastic the Fantastic 5 and like Brooklyn’s ghetto, which he reps here and in almost every song he’s on.

Then he follows it up sequentially with a reference to Grandmaster Flash and the Furious Five who are from the Bronx, or B'Lawn.
