Greasers are a youth subculture that emerged in the 1950s in the United States, particularly in urban areas. They are often characterized by their distinctive hairstyles, which typically include slicked-back hair, and their preference for leather jackets, jeans, and T-shirts. The term "greaser" is often associated with a rebellious attitude and a working-class background. The greaser culture is often depicted in popular media, such as the novel and film The Outsiders by S.E. Hinton. Greasers often had conflicts with rival groups, particularly the Socs, who were seen as wealthier and more privileged. This rivalry highlighted social class differences during that era.
