Sweet Spot (Japanese: スイートスポット) is a Japanese manga series written and illustrated by Yutsuko Chūsonji. Originally serialized in the magazine SPA! from 1989 to 1992, the series follows an office lady (OL) with a passion for golf. The series is credited with originating the slang term oyaji gal (オヤジギャル, literally "old man gal"), used to describe young businesswomen who have interests and hobbies stereotypically associated with middle-aged businessmen. In 1991, Sweet Spot was adapted into an original video animation (OVA) directed by Gisaburō Sugii. Source: Wikipedia (en)
