Ninjuice 

When you earn some street cred as a 90s style Ninja fighting a minotaur in a flannel shirt.

Also a very painful beverage that tastes like a punch to the face.

Make sure you don't get the ninjuice, it will knock you out.

Poetic Injustice 

The evil twin of Poetic Justice. The double standard not applied. A rigged game. Instead of the Poetic Justice of a homicide detective being busted for murder its the homicide detective not being charged with murder even though its pretty obvious that he committed the crime. Or a politician who go busted for tax evasion sponsoring a bill to crack down on tax evaders.

The fact that the judge overseeing the castle doctrine trial is the victim's father and hasn't recused himself is pure Poetic Injustice.
