Internet meme
An internet meme is something famous on the internet such as an image, a video, or even a person. Internet memes are usually created when someone publishes something and that thing is shared widely over the Internet. They sometimes consist of an image with top and bottom text. While spreading over the internet, most internet memes 'evolve' over time, with the original image/video being changed in one way or another by people other than the creator. Every internet meme evolves and has many variants. See: Memes
