The use of the term was first mentioned by early 20th century author Katai Tayama, in his 1909 story Inaka Kyōshi (田舎教師), as a gesture used by the male students in the story. In the story, it gives the etymology as a corruption of akai me (赤い目).

The gesture is used often in manga and anime by tsundere characters.
