– Definition: n. an idea, behavior, style, or usage that spreads from person to person within a culture.
– Used in a sentence: Charles MacKay’s Extraordinary Popular Delusions and the Madness of Crowds is perhaps the Western World’s first serious catalog of memes.
– Why: I am a semiotic and purist dinosaur who thinks the term’s au courant application shortchanges its original meaning. Memes are the heavy-hitters of enculturation. Let’s not confuse them for “captioned graphics,” shall we?
