“This song at first seems quite out of character for Kendrick, talking about money, bitches and guns. But heard in the context of the whole album we can see that this is Kendrick aged 17/18 when he thinks he’s untouchable and just wants to be the big shot. It’s intended to show how different the Kendrick in the story is from the Kendrick we know today” - Rap Genius
This is why Kendrick is the shit. Even his hype shit has meaning.
