A give-and-go, or one-two, is a fundamental maneuver in many team sports which involves two players passing the ball or puck back and forth. The player who has the ball or puck passes to a teammate and then repositions in order to receive a return pass and a scoring opportunity.
It looks like the expression originated in boxing at the beginning of the 19th century:
- one-two blow A combination of two blows with the fists, a short left jab plus a hard right cross, usually to the chin : zipping ''one-twos'' to the jaw (1811+)
