Jock (athlete)
The term jock, when used primarily in the United States, refers to the classic stereotype of a male athlete. It is generally attributed mostly to high school and college athletics participants who form a distinct youth subculture. In sociology, the jock is thought to be included within the socialite subculture, which also contains the preps and Ivy-Leaguers. As a blanket term, jock can be considered synonymous with athlete.
Similar words that may mean the same as jock include meathead, musclebrain, and musclehead. These terms are based on the stereotype that a jock is muscular, but not very smart, and cannot carry a conversation on any topic other than one relating to sports or exercise.
