I never thought it could happen, this rapping stuff
I was too used to packing gats and stuff
These lines highlight the sheer difference in quality of life between his old, grim life and his life after success. It also gives it a magical quality like a boyhood dream he never could have imaged would be realised. As a teenager Biggie wasn’t focused on rapping despite having a talent for it. It also gives a good impression of the reality of impoverished life: ‘Packing gats and stuff’ is set up as the ‘norm’ while ‘rappin stuff’ is something so out of reach of normal people they would never imagine it could happen.
