An infamous person or thing is someone or something that's widely known for being bad or doing something wrong. A movie with an infamous villain might be one people love to hate.
The word "infamous" often comes up when talking about famous crimes, scandals, or troublemakers. It's usually used to describe people who've done something really wrong and got a lot of attention because of it. You might hear someone say, "That politician is infamous for taking bribes," meaning they're known all over the place for doing something shady. Or you could talk about a movie that's infamous for its gore or violence – even if you haven't seen it, people will often mention how bad it is.
Having a bad reputation, disreputable; notoriously bad, unpleasant or evil; widely known, especially for something bad.
Example: He was an infamous perjurer.
