And I don't even push a line, I'm just tryna push these rhymes
In the midst of staying neutral and discrete
He isn’t posing. He’s telling the truth of his life and how he tried to stay out of the gang life, even in Compton. Rather than it meaning he isn’t a poser this might just be him saying that he doesn’t even push a line (coke maybe) as in he doesn’t partake on illegal activities and prefers to rap instead while doing his best to stay “neutral and discrete”.
The line could also mean he doesn’t cross/choose a side of the line, (bang red or blue), he’s not a gangster, he would rather write rhymes. He stays neutral but his mom said if you hang out with Bloods they see you as a Blood, you hang with Crips the see you as a Crip.
Also, pushing a line means, in gang terms, to push a defensive line; to gangbang and pose a defensive line against the bordering rival gangs. So what he’s is saying is that although he was not a gangbanger or even a member, he was still facing the same consequences because of his association. All he was into was writing rhymes.
