Train like Cus D'Amato
The Italian “motto” literally translates to “pledge” in English.
Cus D'Amato was a famous boxing trainer who, among other, was notable for training Mike Tyson in his early years. Nas often references Tyson in his lyrics (The World Is Yours).
This is a play on words which essentially means Nas is going to stay on his game with the same work ethic D'Amato imparted into his trainees.
