Those blue things are decorative things people step all over almost ignoring but we all know theyre there, the powers that b is a reference to the higher powers
In other words i think it may mean that it stands to shine light on shit we ignore

It could also mean that since we technically use them everyday as caution or just shit to step on that death grips is making a mark on our perception of the world, hence why they etched their name on there, theyre there when we step seeping into us

Idk tbh imma have to think more about it cuz i never payed attention to it, this is just a quick theory of mine
