You don't know how little you matter until you're all alone
In the middle of Arkansas with a little rock left in that glass dick
When you’re all alone in the middle of nowhere (i.e. Arkansas) with little of the drug you are hooked on you are going to realize just how insignificant you are. Also, Arkansas is notorious for high use of Crack, and the subsequent dealing in Little Rock.
Little Rock is the capital of Arkansas & also a double entendre here — crack. And “glass dick” is the crack pipe.
Also, Little Rock is actually in the middle of Arkansas, adding to another clever Frank Ocean line.
