When someone is born into poverty and becomes wealthy, they may say they got their money "straight out the dirt". Going from rags to riches without handouts.
Popularized by E-40's song "Straight out the dirt". The lyrics state "I went from nothing to something, I had to make this shit work. Came up from nothing, I got it straight out the dirt".

Hater: "Ha, your dad buy you that?"
E-40: "Nah, I got it straight out the dirt"
