Tic-Tac sign language is a lost art amongst bookmakers in the UK. Very few bookies still use the signals previously popular on racing courses across the United Kingdom.
The signals varied by region but all communicated odds. Some are shouted verbally as well in cockney rhyming slang.
For many punters now involved in horse race betting they are unlikely to encounter Tic-Tac but it can be a fun way to communicate with friends and colleagues while at the races.
