thumbs down 

When Roman gladiators received the thumbs down signal, it meant that a he was to live. It signified that the guards were to put their swords into the ground.

Although I do not remember the name of the program, it was on the History Channel hosted by Peter Weller and he explained that thumbs down has been misinterpreted by Hollywood.
