Some slang has retained significant longevity and while finding its origins in previous conflicts are nevertheless still used by Diggers today. For example, medals were known as "gongs" or "tin". Common sense was known as "CDF" or "common dog fuck" and the morning of the last day in theatre of operations or exercise was known as a "wakey". The small metal spoon found in the Australian Defence Force's 24-hour combat ration pack, called a Field Ration Eating Device, was abbreviated to "FRED" (said to stand for Fucking Ridiculous Eating Device).
