What are mew serials?

Run! If you sell drugs in the school zone
Run! If you gettin' chased with no shoes on
Run! Fuck that! Run! Cops got, guns!
They givin' out life like bird tons
Run! If you ain't do shit, you it
That next felony, nigga, it's like three zip
So, run! Hop fences, jump over benches!
When you see me comin' get the fuck out the entrance!
Run! Fuck that! Run! Cops got guns! Muthafucka..
