Define Immune System Meaning

Immune System
Refers to the human race's unwritten legal code ("The System") that exempts dead people from being responsible/punishable for unwise or offensive action.

Thanks to the rules of the immune system, dead people cannot be blamed or caused to feel regret for prejudiced remarks, as is shown in the following infamous comic conversation from television.
Achmad the Dead Terrorist: I would not kill the Jews... I would just toss a penny between them, and watch them fight to the death over it! Or in the case of a couple Catholic priests, I would toss in a small boy!
Jeff Dunham: Stop it, Achmad! You can't be telling racist jokes on my show! It offends people!
Achmad the Dead Terrorist: Well, I'm already dead, so what do I care?
{{audience guffaws}}
Achmad the Dead Terrorist: SILENCE!!! I KEEL you!
