What is ahegao?
For newbies, ahegao is a type of expression unique to the hentai universe. In both manga and anime, it's quickly recognizable. The girls' open mouths, drooling, tongues out, disgusting eyes and red cheeks.... All taken to the extreme. The shape of the face can also be done at times to give effect to the expression. The different styles of the students can also be significant. For example, one can often find "empty" or heart-shaped pupils. The term used to be better known as "O-face," which appeared around the 1990s. At the time, it was used to describe the facial expressions of porn actresses during orgasm. It wasn't until the 2000s that the term spread fairly quickly among hentai otaku fans, who associated it with their favorite waifus during intense orgasms. Moreover, another kind of emblematic expression was born today, which is even an Internet meme in Japan: the double peace of Ahegao. It is an ahegao expression associated with the peace sign.
