Word of the Day -- Roger

This one is used all the times in the Dens.  Both Steve and Davis were in the miliitary and you will frequently here all of us say:

Roger -- used especially in radio and signaling to indicate that a message has been received and understood.

But that wasn't quite enough of an explanation for me so I did some digging.  Here's some of what I found out...

"Roger" was "phonetic" for "R" (received and understood". In radio communication, a "spelling alphabet" (often mistakenly called a "phonetic alphabet) is used to avoid confusion between similarly sounding letters. In the previously used US spelling alphabet, R was Roger, which in radio voice procedure means "Received". While in the current spelling alphabet (NATO), R is now Romeo, Roger has remained the response meaning "received" in radio voice procedure. In the US military, it is common to reply to another's assertion with "Roger that", meaning: "I agree".  

and...

In the RAF, the expression "Roger Willco" ("received, will cooperate") was used to acknowledge a request or order; It might still be, for all I know. I once had an idea for a television comedy series that followed the exploits of a roguish NCO called Sergeant Willco but was upstaged by Phil Silvers.
