> phrases like "I've got your six" which refer to a circular clock This particular phrase is borrowed from military jargon, as a reference to one's back/behind. For example, in aviation, round clock references are used for shorthand to describe angular directions, with center-you, 9-left,12-ahead,3-right, and 6-behind. Clarity and brevity make this analogy an excellent communication device. Military pilots learn to watch their-"six". At the same time, hearing pilots talk about Romeo Papa makes a side observer wonder how this could be related to Shakespear...if at all.
