Did pirates ever actually say “shiver me timbers”? And why would they be shivering in the Caribbean, anyway? Actually, this saying has nothing to do with being cold, and pirates probably didn’t say it. The phrase goes back to the 1700’s and was popularized in books such as Robert Louis Stevenson’s Treasure Island. Shiver, in this sense, means “to split in two.” Shiver me timbers, in the imagined pirate lingo, refers to a storm or siege splitting the wooden beams of a ship. This is part of a complete episode.
