I always thought they were talking about Popualtion Clique for some reason. Remember, Sunz Of Man were signed to Wu-Tang Records at first, but then they left to another label, so the Population Clique album never came out. The song "Wake Up" was originally a Population Clique song (the title said Population Clique: "Wake Up", on the original vinyl), but then the song appeared on KillArmy's album. This is what I think.

Note: This is just my understanding.
