meme n (mëm): A unit of cultural information, such as a cultural practice or idea, that is transmitted verbally or by repeated action from one mind to another. From the Greek mimëma, something imitated, from mimeisthai, to imitate.

My favorite example of a meme comes from Heith Michael Rezabek: My favorite example of a crucial meme would be “fire” or more importantly, “how to make a fire.” This is a behavioral meme, mind you, one which didn’t necessarily need a word attached to it to spring up and spread, merely a demonstration for another to follow. Once the meme was out there, it would have spread like wildfire, for obvious reasons… But when you start to think of memes like that — behavioral memes — then you can begin to see how language itself, the idea of language, was a meme. Writing was a meme. And within those areas, more specific memes emerged.
