Got on your bullet proof?
Well mine's goin' right thru

Meaning

Are you wearing a bullet proof vest? It won’t matter because my bullets are going to penetrate it.

If you are shooting an illegal weapon at a cop or other thug, you might as well also have some crazy ammo to go with it. Bullets with full metal jackets or teflon coated bullets are known to penetrate “bulletproof” vests.
