According to All Hip Hop:
Chief Keef may be the realest rapper out, depending on how you define real. I just don’t think he cares about anything. The GDs are feared just about everywhere, but Keef ain’t one to be afraid, I guess. He went back and forth on twitter for all the world to see. I guess the best thing about this is that maybe they will have a good ol’ fashioned fist fight. This guy Lil Jay has vowed to avenge the death of Lil JoJo.
