In McLuhan's terms, a "cliché" is a "normal" action, phrase, etc. which becomes so often used that we are "anesthetized" to its effects. McLuhan provides the example of Eugène Ionesco's play "The Bald Soprano", whose dialogue consists entirely of phrases Ionesco pulled from an Assimil language book: "Ionesco originally put all these idiomatic English clichés into literary French which presented the English in the most absurd aspect possible."
