A mustache is a long piece of hair that grows above your upper lip. It's usually thin and can be trimmed or styled in different ways.
When people talk about someone having a mustache, they often mean it as a distinguishing feature of their face - like a beard but just for the top lip. Some men choose to grow a mustache as a fashion statement or because it suits their personality. Others might get one as part of a cultural tradition. Either way, a well-groomed mustache can be quite eye-catching!
