Animation memes are short animations of a character dancing or sometimes singing along to music with the intent to be spread or repeated by other animators with their own characters. They usually involve simple, repetitive actions. (animation-meme.fandom.com)

This internet trend(?) was what thaught me everything I know. I've started making them in 2017 and never stopped. I find them really fun and relaxing to do especially after a long project. You don't have to try and be original because you're referencing a template.
