A (navy) call made when you have to get past someone in the passageway, or to announce your presence in the room.
As Roof enters the mess he would call "backs" which would result in a response of "backs" by every member in the mess. A non-response generally means that the paticular members sexuality is questioned.

"Backs, big unit coming through" as Parko or Reid pass you on the way to 2 Mess.
