isn't a watch word, a code word? as you go on patol, or watch, you are told the word of the day. when you detect an intruder, to tell friend from foe-- you ask him the watch word..

I believe that's a password. An old story from WWII what that the Allied forces in the Pacific would pick a password like lallapalooza because it was impossible for most Japanese to produce the <l> sound.

Or was that wordapalooza?
