(Rolling with that flow swamp)
His flow is swamp, a descriptor created by Earl himself here in the song Between friends, probably to describe it as grimy and nasty.
Earl has stated that he likes his beats “muddy” which would be like a swamp. Muddy beats are distorted which is a lot of what this album has on it.
