"beadwindow" is a term from my military days. if that word was said over comms, it meant that some sensitive info was inadvertently mentioned on the net and everyone needs to be advised. it was also followed by a number combo that gave specific data relating to the nature of the info. of course, we used it (or some other previously agreed upon term) to let all the guys know that one of the jefes was listening in on our team comms and to keep things business-like.
