Internet memes are humorous images, videos, or text that spread rapidly online, often modified by users. They typically reflect cultural trends, social commentary, or relatable experiences, making them easily shareable across platforms like social media and forums. Memes can take various forms, including image macros, GIFs, and video clips. They often rely on a specific format or template, allowing users to create their own versions. This participatory nature fosters creativity and community engagement, as people contribute their interpretations and variations of popular memes.
