What does "Untitled 2 (Blue Faces)" by Kendrick Lamar mean? Pt. 1

When I started, I think the first recommendation I got for a song to explain was anything from To Pimp a Butterfly by Kendrick Lamar. Unfortunately, it'd already been out for a while, so I wasn't sure that it would be a good idea. So, I've been waiting a while to be able to explain one of his songs, and finally I have an opportunity to do so!
