It's about Beatz. Will said so. It's good that you can interpret it in your own way, though. And it's "infect your perfect sliced up skin" because John flew through the windshield when the car crashed, thus resulting in a bloody mess as you can imagine. Who knows what Will was thinking when he wrote the things that don't seem to relate at all, but trust me, it's about Beatz. The rest that doesn't seem to relate is probably metaphorical.
