Song on the radio

[cujo23]

I heard a song late on the radio and dont remember all the lyrics but the chorus said something like "in my school" or "in my own school" and it sounded like an older guy singing it, like a sample, during the verse it was a rapper and the only thing I remember is something about sitting in his car "lookin like a PI" I dont know if is was mexican but I know it was hip-hop, late at night they sometimes play mexican hip hop. Good song, Please Help
