Lol. A meme is a thing (usually an image or an idea or saying) that basically goes viral and is indeed overused. I am a huge fan of image memes. For example, Doge or Pepe the Frog. There is the Troll Face. Or the infamous Spiderman memes. The nyan cat is also an example. Sanic, Dankey Kang, and Lonk are examples. Does that help? :3
