means Plays on a seesaw, or moves repeatedly up and down or back and forth between two states or positions.
from A reduplication — that playful English habit of echoing a word with a slight twist (think flip-flop, zigzag). The popular guess ties it to 'saw,' as if mimicking the rhythmic push-and-pull of two sawyers working a long blade, one rising as the other falls. That motion certainly matches, but the word is more likely just rhythmic nonsense built to sound like the rocking it names, possibly from the French 'ci-ça' (this-that) chanted by laborers — though that link stays a maybe, not a fact.
