The Art of Gang Fu

I learned a term in the Navy that I still think is funny to day: Gang Fu

I can vaguely remember the Petty Officer who was teaching a lesson about boarding another ship. I remember it because it was a great lesson, and it has to do with piracy. Before boarding a ship, the idea is circle around the boat first to make sure that the crew isn't hiding around back side waiting to "gang fu" the boarding party.
