Chinaman

A Chinaman could be mean, literally, a "man from China'. (DW: The Talons of Weng-Chiang)  However, it had an entirely different meaning relative to the sport of cricket.  In that context it was, as the Fifth Doctor once explained to Turlough, a "off break ball bowled by a left-hand at a right-handed batsman". (BFA: Phantasmagoria)
