Artie 5ive builds this whole track out of one sound. "Ho una Glock, tengo una Glock / Che fa 'bop, bop, bop, bop, bop, bop'" (I have a Glock, I keep a Glock / That goes 'bop, bop, bop, bop, bop, bop'), and a few bars later the same syllable belongs to the sound system instead: "Queste casse fanno 'bop, bop'" (These speakers go 'bop, bop'). The gun and the speakers end up making the same noise, which is the joke and the threat in one.
Around that hook the verses wander somewhere odder than Milanese drill usually goes.

The second verse drops the swagger for a few lines and looks straight at the woman he is with: "Lividi, tuo padre ti ha lasciato solo lividi" (Bruises, your father left you nothing but bruises). Then the shutter comes back down. "Io e te non siamo niente, né fidanzati o amici" (You and I are nothing, not partners or friends). He explains exactly why he leaves in a hurry, and then he leaves.
