There are a wealth of different codes in use to obfuscate the planned tactic. One scheme uses a set of three words which share no letters (e.g. "THAMES ROWING CLUB" or "THE BIG DON"). The first word will signify the front of the line, the second the middle, and the third the back of the line. The call will then incorporate a letter from one of the words, indicating where the throw will be made. There are also numerical codes, and more esoteric ones involving anything from the number of legs on animals to the personal characteristics of people known to the team.
