"I'm Life Litter's official stripe getter" (Earl Sweatshirt – Cool) | rejected

considering the line above, earl could be claiming he is the official source of alcohol for this underage group. The “stripe” could be referring to Red Stripe, the imported beer.

The “trees” can not only represent the trees in the woods, but adults that are taller than them. They could also think they are adults since they are “tripping balls”
