Yesterday, dictionary.com‘s Word of the Day was “meta,” which it defined as follows:
1. pertaining to or noting a story, conversation, character, etc., that consciously references or comments upon its own subject or features, often in the form of parody: A movie about making movie is just so meta—especially when the actors criticize the acting.
2. pertaining to or noting an abstract, high-level analysis or commentary, especially one that consciously references something of its own type.
Two thousand years of using “meta” (from the Greek μετά, “beyond” or “after,” e.g. Aristotle’s Metaphysics) to denote something greater than, is trumped by a few nihilistic hipsters.
Look, dictionary.com, if you want to note that “meta” is commonly used by would-be clever twenty-somethings, then please note such a use as definition #2, or as “slang.” For “meta” as a parody, rather than as a “high level analysis or commentary,” is nothing but slang.
