The word "Meme" is autological, meaning it describes itself. According to researcher Curry Chandler "biologist Richard Dawkins introduced the word “meme” to refer to a hypothetical unit of cultural transmission"(MEMES, ENTHYMEMES, AND THE REPRODUCTION OF IDEOLOGY). We share our ideas through memes on the internet so we can communicate and relate, they're well-liked because we enjoy being personable and knowing that others have experienced what we have. According to legal scholar Jake Balkin, "Much human communication requires the parties to infer and supplement what is being conveyed rather than simply uncoding it"(Cultural Software p.51). Memes are rhetorical so they rely on prior knowledge for understanding. That also means that memes can be globally understood or only understandable to a specific group of people. Memes are not only available in one type of format, memes can be videos, images, or blatant jokes, the true "meme" is the general idea that is spread which is why so many sub-memes or "children" are created from the mother meme. In actuality, a meme is an art that conveys an idea of understanding through rhetoric.
