A sport in which extremly fit people with a hell of alot of metal strenght run until they faint. After a race, throwing up is common, leading to the saying, "If you don't throw up, you didn't try hard enough." Cross country runners are often mocked for having enough balls to wear short shorts, but cross country runners usually don't mind because they go to practice everyday and talk it up with girls.
runner one "Man, I just threw up after my cross country race!"
runner two "Good job man!"
