A meme (/miːm/ meem) is an idea or belief which spreads because one person copies it from another.

One idea is that culture builds in a way similar to living things. An example would be how viruses spread to different organisms. Memes change as they go, creating controversy, and sculpting society. Just as a virus would, memes evolve from their state, being photoshopped, and exaggerated. Memes can be about anything.
