My fifth grade teacher taught us the "sheet shank." That was about 40 years ago. Up until about a year ago, I always referred to it as the "sheep shank." I always wondered what it could possibly have to do with sheep.

To add to the confusion or maybe explain it.

Sheep shank, knot used to shorten a length of rope, didn't know about the knot being used for restraining sheep :confused if the ends of the rope are not under tension the knot comes undone quite easily, only about 47% efficient
Sheet Bend, used for joining two lengths of rope together
