What is a Meme?

An idea, behaviour, or style that spreads from person to person within a culture. A meme acts as a unit for carrying ideas, symbols, or practices that can be transmitted from one mind to another through writing, speech, gestures, rituals, or other imitable phenomena. Supporters of the concept regard memes as cultural analogues to genes in that they self-replicate, mutate, and respond to selective pressures.
