In the book Flatland, women (in Flatland) must wiggle back and forth while they walk, and emit a constant sound, called "the peace sign."

This is because Flatland women are one-dimensional lines, with a single eye at one end. Because they are lines, they are invisible at a distance, and can therefore pierce and seriously injure or kill men. Which are of higher dimension, various polygons.

Your post prompted me to look up Flatland and then watch the movie.
