Casting live bait is the process of putting a hook through the rather delicate nose of a live anchovy(tuna bait) and then casting it hard enough to get it away from the boat without tearing the hook out of the anchovy's nose.

The tuna shuffle is the act of slowly moving along the rail of a 50'+ boat in unison with 40 other guys as you all follow the anchovies just cast out as the boat gently drifts downwind and the anchovies are slowly pulled away from the boat. Everyone doing it correctly prevents line tangles.

HOT RAIL is what you scream as you chase a freshly hooked tuna up the rail as you go over/under all of the guys doing the tuna shuffle to prevent your line tangling wit theirs.

I won't bother to list the terms that are used when best efforts to do the above fail and the line attached to tuna ends up tangled with a dozen other lines. This is all much more entertaining in real life.
