Meme

A meme is an idea, behavior, or style that spreads from person to person within a single or multiple culture. While genes transmit biological information, memes are said to transmit ideas and belief information.

A meme acts as a unit for carrying cultural ideas, symbols or practices, which 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.
