6. A number of old words for movement involve a thing used or imagined in the movement - among these is waddle, the motion done by people walking on wads of thick cloth strapped to their feet as a treatment for bunions. Paddle, to push oneself along with a pad, is also in this category - a lesser known one being to boatle, which only survives now in the phrase "to bottle it" - actually "to boatle it", i.e. to run away in a boat.
