Rookie

In contrast with a veteran who has experience, a rookie is typically considered needing more training and learning, though they may bring a new outside expertise to a job.

The Oxford English Dictionary states that the origins are uncertain, but that perhaps it is a corruption of the word recruit.

Examples in baseball include players having to dress up in very strange costumes, or getting hit in the face with a cream pie; a traditional rookie's "hazing" procedure in American football involves taping players to a goalpost and dousing them with ice water, Gatorade, and other substances.
