This character is refered to as a Jock.
The term jock, when used in the United States and Canada, refers to the classic stereotype of a male athlete. It is generally a negative stereotype, and is 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.
