This is Madness! Oh, no, this is Sparta. It is a catchphrase usually used in images that parody the scene from the film 300 where the main character Leonidas, King of Sparta, declines peace with the Persians by shouting at the Persian Messenger "This is Sparta!" and kicking him into a large well proceeded by the killing of the other Persians. Caution This Is Sparta Sticker, in case you need a strong phrase to say.
