Ahegao

Ahegao (アヘ顔, Japanese pronunciation: [ahegao]) is a term in Japanese pornography for a facial expression of characters (usually women) during sexual arousal or an orgasm, typically with rolling or crossed eyes, protruding tongue, and slightly reddened face, to show enjoyment or ecstasy.

Pornographic magazines used the word to describe the facial expressions of female live-action porn actresses during orgasm.

By that time, the facial expression was featured in regular pornographic videos during the popularization of hentai fetishes in the real-life sex industry.
