Nigga mouth slow-leakin', air him out, no charge
That's free, no prod, that's "G code" ya'll

from Lil Wayne (Ft. Juelz Santana) – Rewind Lyrics on Rap Genius

Meaning

If someone is ratting on Juelz or one of his associates, it will not be a problem to have some holes put into him, in order to “air him out”. Juelz reaffirms that he won’t charge anyone for giving them good advice: kill snitches. Rather, he reaffirms that it is expected as part of the code of the streets carry out such killings if someone is speaking to the police of feds.
