Glock nineteen for casket and flower moves
For chumps tryna stop my flow
And what they don't know will show on the autopsy

Meaning

His gun is a boon to the casket and flower industries (via the funeral industry)

The coroner will find bullet wounds in the bodies of chumps who tried to stop Big (and didn’t anticipate getting shot).
