1. A petition or other document signed by several persons in sequence, so that no one can tell who was the first to sign it. For example, We decided to send a round robin to management to protest the new rules about work hours. This term originally referred to a grievance presented by seamen to their captain, called round because of the circular sequence of names, but the source of robin has been lost. [Early 1700s] 2. In sports, a tournament in which each player or team plays against all of the others in turn. For example, The club always holds a tennis round robin on the Fourth of July. [Late 1800s]
