Get the Go old testament on your ass mug.
Meaning that you are going to be beaten or killed for whatever transgression you committed. Old testament of the Bible speaks of terrible punishments given by God.
Someone deliberately scratches your car. You tell the person that you are going to go old testament on your ass. You lay an ass whopping on him and you have effectively 'gone old testament on his ass'
