American prison term. It means person will be shanked in the shower. Bleeding out before guards even notice that he was late for the breakfast.
This shithead got greenlit yesterday.
When a `hit` is put out on you.
You have been greenlit
prison lingo when a dirty cop wants a prisoner dead he will have him green lit which means he gives the okay for another prisoner that owes him a favor to shank this guy to death in the showers
when detective vic mackey wanted armadillo's brother dead he had him green lit then some black dude that owed vic a favor stabbed him in the shower
