Deadcenter

Off the deadcenter position, the spring retains the flap and the locking pawl in their locking positions.

And with the hook placed deadcenter in the back, rather than in the mouth or tail, the fish can carry the load without swimming suspiciously off-kilter.

Turn the engine so that one of the cranks is about ten degrees beyond the top deadcenter.

He about deadcentered your pocketbook didn't he?
