Youth subculture is a youth-based subculture with distinct styles, behaviors, and interests. Youth subcultures offer participants an identity outside of that ascribed by social institutions such as family, work, home and school. Youth subcultures that show a systematic hostility to the dominant culture are sometimes described as countercultures.

In the United States and Canada, a jock is a stereotype of an athlete, or someone who is primarily interested in sports and sports culture, and does not take much interest in intellectual activity. It is generally applied mostly to high school and college athletics participants who form a distinct youth subculture. As a blanket term, jock can be considered synonymous with athlete. Jocks are usually presented as male practitioners of team sports such as American football, basketball, baseball, lacrosse, soccer, swimming and ice hockey.
