One of the Navarasas.
This rasa represents the revulsion that the character feels, on seeing unpleasant sights or things. Jugassa or disgust is the basic emotion here.
While portraying this rasa, the character stoops his neck forward slightly, pulls his eyes inward to make them smaller, lowers his eyebrows, blinks his eyes, and pushes his cheeks and lips downward, all in a highly exaggerated fashion.
