(written as Jock)a Scottish soldier
- noun a disc jockey. A piece of American radio jargon adopted in other English-speaking areas in the 1970s.
- noun an athlete or sportsman. This campus term can now also apply in some cases to sportswomen, in spite of its origin as a shortening of jock strap. Although it can be said affectionately and is a term used by sportsmen about themselves, the word often has overtones of excessive heartiness, brawn, aggression or lack of intelligence.
