This expression usually (but not always) indicates a state of exaggerated sexual pleasure. It can also indicate craziness, drug influence, or asphyxiation.
Not to be confused with torogao, which is an expression that usually indicates a state of trance-like pleasure. Ahegao is a more wild expression. Basically; is she looks manic or like she’s laughing it’s this expression, if she looks sleepy or zoned-out it’s the other one.
