They say don’t buy the belt and I got it
They say don’t get the Rollie and I bought it
Nigga, I’m balling

You cannot tell Schoolboy Q a god damn thing! He is going to ball hard cause that is what he wants to do! If he wants to buy something to look cool, he is going to do it whether you feel its a wise investment or not.
