么么哒

Chinese onomatopoeia for a kiss, written 么么 with the cute sentence-final particle 哒. Language Log observes that it corresponds to the sound "mua" but is not identical to English "mwah": it is often attached as a suffix and has existed independently for a long time. Chinese media guides describe it as used by teenagers and adults to express love and fondness, not only between couples but also among family and friends. Its form parallels 萌萌哒 ("cute"), and writers suggest 萌萌哒 may have developed from it, though the origin of 萌萌哒 itself is hard to trace. The first use of 么么哒 is not documented.
