"Rain check" in lyrics
Let's forget what was said and give pain a rain check
Like before, when we stood tall over our callous sins.
See, all of your demons became my demons
On your front line I fought.
Or will these blisters become targets of the scorpion king's sting?
Because the poison invades the veins to the stages of Hume
I'll take a rain check in the same breath of a checkmate - in three moves
I know everything is everything and nothing's still something else
And shout-outs to all my niggas with escape plans
Uh, twenty bands, rain dance
We could either rain check or we can make plans
Pockets loaded, rocket loaded, okay, let's rock and roll this
