@robinmujician Interesting — I’ve always considered a meme to be an idea transmitted between people, and memetics the study of how ideas travel between people. The argument being that uncommunicated thoughts aren’t very meaningful to anyone except the thinker, and the physical expressions of memes are creative works in their own right rather than memes — the meme being the idea that the creative work transmits.

Never really considered it as applying to behaviours but it makes a lot of sense, and is in the official definition: https://en.wikipedia.org/wiki/Meme
