First appeared in the 1990s. Varied theories regarding the term's derivation.
Two possible derivations are attributed to bouncers at night clubs, as slang abbreviations to indicate a young woman who was underage and should therefore be denied entry.
- From 高校生 (kōkōsei, “high-school student”) + ギャル (gyaru, “gal, young woman”, originally referring to someone not a minor).
- From 格好 (kakkō, “appearance, seeming”) + ギャル (gyaru).
Another possible derivation is attributed to the mass media.
コギャル (rōmaji kogyaru)
- a teenage girl participating in a particular subculture in Japan, with a tendency towards being obsessively trend-conscious, kogal (kogyaru)
