As the world turns, I spread like germs
Bless the globe with the pestilence
The hard-headed never learn
Pestilence refers to any powerful infectious disease, tying back to the first line. However, Mef also says he’s going to “bless the globe” with it, which is a biblical reference (God threatened pestilence as a plague in Egypt, Pestilence is also the final Horseman of the Apocalypse).
As the world turns Meth and his clans will continue increase their numbers through procreation and education. And in spreading their message and masses they’re blessing the world. The underclass is often seen as pest/vermin etc.
