When playing ping pong, if the ball barely nicks the edge of the table it is called a chinese baby because it strongly resembles the sound of a chinese infant.
Player 1: Gee Willakirs! What a shot!
Player 2: That shot was a Chinese Baby because it barely nicked the edge of the table making it impossible to return.
Player 1: Haha because it sounded like a Chinese baby! jk lol. No but really..
