A zombie is an imaginary creature that's dead but moves around and tries to eat people. You might have seen it in movies or TV shows.
In popular culture, zombies are often used as a way to tell scary stories. They're usually slow-moving and not very smart, so they're not too threatening. In books, movies, and video games, zombies can be the main enemies that heroes have to fight against. Sometimes, zombies are also used as a metaphor for things like overconsumption or mindless crowds. For example, if you think of people rushing to buy something on sale as "zombies" because they're driven by instinct rather than reason, it's a fun way to describe the situation.
