“When I use a word,” Humpty Dumpty said, in rather a scornful tone, “it means just what I choose it to mean—neither more nor less.” From the O.E.D.: Charade (2). In extended use: something (esp. a dramatic entertainment) regarded as resembling a charade in some way, esp. in lacking sophistication. Later more usually: an (obvious) deception; an absurd, shallow pretence; a travesty. I think one would be better off improving one's grasp of English through sources such as The Atlantic than by pretending to have a superior grasp of it.
