Rap phenomenon, defyin' the rules of gravity
In science a phenomenon is “a fact or situation that is observed to exist or happen, especially one whose cause or explanation is in question.” In this sense, Game is saying he’s as mysterious and unpredictable in the rap game as a strange scientific phenomenon, such as something that defies the law of gravity.
Game is a rap “phenomenon” in the sense of being “a remarkable person…” in the rap game.
Also note that “Rap Phenomenon” is a song by Biggie and was a nickname he gave to himself.
