a. (alternative spelling of gaga English) interj. The noise of a baby trying to imitate speech.
Ga-ga ( literally 'touch-touch') is a variant of dodgeball that is played with one ball. The game combines dodging, striking, running, and jumping, with the object of being the last person standing. Players hit the ball at each other with their hands, and are eliminated if the ball strikes them on or below the knee. The game can be played by a group of individual players or with teams, as well as in one-on-one matches. Rules, ball types, pit surfaces, and pit sizes can vary widely at different venues.
