I know the last couple of lines kinda fell out of the pocket

Royce is implying that he knows the last few lines above were both random, deep and valuable. He says “fell out of the pocket” — you never plan on something falling out of your pocket it just happens…
It also refers to the flow falling out of the pocket, or off the beat. “In the pocket” means riding the beat perfectly, good flow, etc.
