Open the mail, starin' at the check
Enough to make you throw up, man it's gross what I net
In financial terms, “gross” means the total amount, and “net” means total take away loss/expenses (basically, how much you actually earn). Saying “it’s gross what I net” suggests that he’s not losing any money to taxes — his net income is his gross pay. This could in fact be true if he sends his money to offshore banks in tax-free zones.
