Both my wife & I remember our parents using a word (one family from New York/Ohio & the other from California/Colorado). The word is calipigate -- used in one family to mean a syncopated rhythm & the other to label a syncopated gait. A friend challenged my wife's usage of the word the other day, which had caused us to search all our online & analog sources for it. Even the OED offers no trace of it, though we're thinking it may have been some oddly unrecorded word that originated in callipygian (having shapely buttocks).

Have any of you run into calipigate? Are we just nutcases who manufactured shared memories of a non-existent word?
