軽薄短小
kei.haku.tan.shou
Literally: light – dilute – short – small
Alternately: Of a thing: small and light. By metaphorical extension, a person whose character is shallow; a hollow person with no substance to them.
Notes: The physical meaning has apparently become widespread since around the 1980s, as a positive trait to be sought after in goods such as electronics.
