A meme is a piece of content, often humorous, that spreads rapidly online. It can be an image, video, or text that captures a funny or relatable idea. Memes often use popular culture references, like celebrities or TV shows, to connect with audiences. They are shared across social media platforms, making them a fun way for people to express their thoughts and feelings. Memes can evolve quickly, with users adding their own twists or variations. This creativity keeps them fresh and engaging. For example, a simple image of a cat might be turned into countless memes, each with a different funny caption.
