I've been grinding since a day old
Now I'm older but my mama don't think so
Tyga’s mother doesn’t think he’s wiser, thinks he’s still a child in the world. Being older in age doesn’t necessarily make him more mature for it, and his mom still sees him as a child. This mixtape came out when Tyga was 21, an especially notable age considering that most age-based restrictions on substances, activities, etc are removed by that age.
