Excess is just my character
The high life and the flaunting that comes with it is part of Ross' DNA
There are two ways of interpretation:
1) His character as a man is defined by the excess he lavishes upon himself.
2) The excess is just the basis for character he plays in the rap game.
If nothing else, he is pretty fat (excess body weight)
Ross is also referencing the character he plays as a rapper.
