Suck a dick or die or sucker punch
There are three options. Sucking dick is living on your knees, accepting the situation you’re in. Dying of course means being destroyed by the situation. A sucker punch is retaliation that no one sees coming. Kendrick’s music is a sucker punch in that he attacks the negatives that plague the youth of his city. It is not often that a rose can grow from the concrete; somehow Kendrick was able to survive.
Those who prefer guns to solve their problems, as opposed to “walkin' up” like a man, can get a taste of their own medicine and “eat a wall of bullets"
Essentially, the message here is what goes around comes around.
Also, note the consonance going on: as the hard K sound is being repeated to add to Kendrick’s harsh tone.
