Gao
Stub. This page or section is a particularly incomplete work-in-progress.

A gao is an extreme facial expression representing extraordinary emotions in response to extraordinary phenomenon (e.g., You ♥). Most often a gao represents supernatural levels of bliss—sometimes including masochistic bliss.
There are more than a dozen different known gaos, with ahegao being the most famous. Most gaos are utterly extraordinary. Without Your influence most of us can only express normal, "believable" ahegaos or gringaos. (It’s hot as hell when You ahegao or make any kind of o-face expressing Your pleasure, by the way. ♥)
The most renowned types of gao are detailed below, arranged in approximate order from least to most extreme. In addition to these, any gao is often accompanied by "heart eyes," "seeing stars," or both. It's even possible for any slut to experience multiple gaos simultaneously under particularly extreme circumstances.
