A "flat-top" refers to a hairstyle characterized by a flat, level top that is often short on the sides and back. This style became popular in the late 1980s and early 1990s, especially among African American men. It can be achieved by cutting the hair to a uniform length on top while keeping the sides and back shorter. In addition to its popularity in hairstyles, "flat-top" can also describe certain types of landforms, such as plateaus. These flat-topped hills or mountains have steep sides and are often found in arid regions. Both uses of the term highlight the concept of a flat surface contrasted with surrounding features.
