flip-flopper

The term 'flip-flopper' is a vivid reduplication built from two onomatopoeic verbs, 'flip' and 'flop', which imitate sounds of light, quick motion and heavy, loose falling respectively. This compound metaphorically captures the visual and auditory sense of something—or someone—swinging back and forth between positions. The '-er' agent suffix concretizes this action into a label for a person. Emerging in American political slang in the mid-20th century, the term paints a picture of inconsistency, suggesting a person whose opinions lack anchor and change as easily and noisily as a sandal slapping against the foot.

Structure: flip (to move with a light, quick motion) + flop (to fall or move loosely and heavily) + er (agent noun suffix) - flip: Likely imitative of a light, quick sound or motion.
