Nope. I learned it from another sailor who was doing it. At the time I
didn't know what it was called, or if it even had a name. I asked a
few other sailors about the technique when I got home, and some of
them recognized what I was talking about.

sailor?

You should have asked him where he saw it and why it was used. Story sounds
fishy, like a lot of things from BB.
