Bodies on top of bodies
IV's on top of IV's
There was so much killing that corpses were everywhere, piled on top of each other. And the hospitals were packed with the wounded and dying.
IV is the double entendre in this line. IV is the Roman numeral for 4, thus Kendrick is saying that there were .44’s everywhere. Additionally, IV is the acronym for the intra-venous drip inserted into many hospital patients' arms to get liquid directly into the bloodstream. Gunshot victims would almost certainly be given blood transfusions by this method.
