What does the song "18 in Life" mean?

18 and life is one of the greatest song ever. It talks about how a boy grew up and committed a crime. 18 and life is how you will go to prison to serve life for the crime that you have done. (only 18 and up can be convicted at that time, don’t know right now) so when it says 18 and life you got it, 18 and life you know….. and its 18 and life to go. It is serving life sentence for the crime that he did, especially now that he is 18. ***note that the shooter is already 18 at the time the crime was done so life imprisonment is applicable to him***
