Meme or Internet meme is an art form, idea, behavior, style, activity, concept, catchphrase, or piece of media that spreads, often as mimicry or for humorous purposes, from person to person via Internet, with the aim of conveying a particular phenomenon, theme, or meaning represented by the meme. A meme acts as a unit for carrying cultural ideas, symbols, or practices, that can be transmitted from one to another through the audio-visual media which include writing, speech, gestures, rituals, or other imitable phenomena with a mimicked theme. In the world of Internet, memes frequently come and go, but one internet creation has had surprising longevity.
