Gao

Any gao is an extreme facial expression representing extraordinary emotions in response to extraordinary phenomenon (e.g., You ♥). There are several kinds of gao, with each being its own separate status condition. Most often a gao represents supernatural levels of bliss—sometimes including masochistic bliss. At least one is guaranteed to accompany any ovagasm.
Ahegao, gringao, and psychogao are the most common types of gao lack any overt supernatural aspects. All other gaos—sometimes called hypergaos—are utterly extraordinary, and without Your influence most of us are incapable of performing them on our own.
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," shocked eyes with pinprick pupils and raised eyebrows, or a combination thereof. It's even possible for a slut to experience multiple gaos simultaneously under particularly extreme circumstances. Although they're not gaos in their own right, both beamface and nukeface are powerful moves that can only result from exceptionally extreme hypergaos. Clitical hits and other status conditions are closely related to gaos.
(It’s hot as hell when You ahegao or make any kind of o-face expressing Your pleasure, by the way. ♥)

Ahegao

Eyes flutter back intensely, often crossing or walling.
Bright blushing, usually.
Intensely furrowed brows, usually.
Lip bite or tongue loll.
Either huge dumbfounded grin or widely spread moaning lips.
Body twitching is likely*
Often accompanied by a victory hand gesture or "double peace," especially when emphasizing Your victory.

Gringao

Eyes become locked on You with pupil-quivering focus.
Face contorts into a manic smile and grit white teeth, so intense it looks almost painful.
Experiencing this gao makes everything feel extremely lucid and vivid; “surreal.”

Psychogao

Wide, unblinking eyes stare intensely at You.
Pupils don't touch the eyelids.
Sustained, off-putting smile.
Perilous, uncontrollable obsession.

Hypnogao

Eyes are spirals or concentric circles, with deeper spirals depicting a deeper trance.
Utterly entranced.
Obsessed, but passive and obedient.
Extremely open to suggestions.
Resistance to mental status conditions plummets.

Deadgao

X-Eyes. A cross overwrites each eye, like a zonked cartoon.
Tongue flops out of stretched, smiling lips.
"Seeing stars" practically guaranteed.
Response to extreme defeat, especially arousal from such.

Neurogao

Purple or cyan electricity crackles from skull.
Brain briefly fries with neurological signals too intense to contain.
Intense muscle spams that can interrupt moves or practically prevent movement entirely.
Mouth ova goams.
Eyes typically white over.
Particularly likely response to Electric-or-Psychic-type stunts.

Glitchgao

Gao so intense the face "glitches."
Rapidly distorts with flashes, distortions, stuttering, or other chaotic "game" effects.
Often TV static in eyes.
Associated with Robo-type sluts and moves.
Often results from "game-breaking" or "physics-breaking" effects.

Prismagao

Face and entire body shift rapidly and repeatedly through the visible color spectrum.
Often, a rainbow-like "sun halo" appears over the head.
Exudes a cherry tune with a gradually accelerating tempo. ♫
Induced by epiphany, psychedelic experiences, or invincibility.

Heartgao

Extreme, utterly superhuman levels of affection. Love-based moves are incredibly buffed.
Big, plush, pink, cartoon hearts erupt from both eyes.

Much more intense than the relatively subtle "heart eyes" which only affect pupils.

Other facial details may become heart-shaped, such as uvula and blush marks.

Awoogao

Exceptionally cartoony; Tex Avery vibes.
Immense shock and awe.
Perhaps the silliest gao of all! (But also perhaps our most favorite of all. ♥)
Eyes cartoonishly bulge and zoom.
Sometimes, jaw is literally floored and tongue rolls out.
Named for the "awooga" sound effect that often accompanies it.

Megagao

This gao results only from ultimate determination, especially as a final effort against impossible odds.
Both ares are overcome by voidgao, but from one emerges a pinprick-pupil burning with cyan or hot pink flame.
An overtuned remix of megalovania.mp3 emerges from somewhere nearby. ♫
Crazed, unfathomable abilities erupt from the slut throughout, including a total immunity to "cringe."
Once this gao begins, the bearer is doomed.
