Young'n never pump fake, and you'll get past the blitz
And keep ya whole hood on flip, like old box-spring
Pissy mattress shit, low old box of things
Strictly glassy shit,
Continuing the football metaphor. Pump faking in terms of drug dealing means “slacking off”. The blitz would be the police trying to catch you
Keeping the hood on flip is making money. He compares this to kids in the hood who would jump up and down (and sometimes flip) on discarded mattresses
The “Pissy mattress” reference is also relevant here because, when an old mattress has been stained or is worn on one side, it can be flipped.
