"The word meme originated with Richard Dawkins' 1976 book The Selfish Gene. Dawkins used the term to refer to any cultural entity that an observer might consider a replicator. He hypothesized that one could view many cultural entities as replicators, and pointed to melodies, fashions and learned skills as examples. Memes generally replicate through exposure to humans, who have evolved as efficient copiers of information and behavior." (Wikipedia)
Viral social media content is itself a meme, as social media allows for the rapid sharing and spreading of information and ideas from person to person. There are numerous examples of memes, some of the most popular being the Coke Happiness Machine, the ALS Association's Ice Bucket Challenge or “Tarder Sauce” the Grumpy Cat.
"An idea, behavior, or style that spreads from person to person within a culture". A meme acts as a unit for carrying cultural ideas, symbols, or practices that can be transmitted from one mind to another through writing, speech, gestures, rituals, or other imitable phenomena with a mimicked theme. Supporters of the concept regard memes as cultural analogues to genes in that they self-replicate, mutate, and respond to selective pressures. (Merriam-Webster Dictionary / Wikipedia)
A "meme" is a virally-transmitted cultural symbol or social idea. A meme (rhymes with "team") behaves like a flu or a cold virus, traveling from person to person quickly, but transmitting an idea instead of a lifeform. (About.com)
