There are no femcels. Females by default can not be Incel.
In the past I believed that there were exceptions. Like a morbidly obese female, or a female who suffered some kind of animal attack or accident and ended up with facial disfiguration. Even Down Syndrome or severe mentally unable people.
But now I know that I was wrong, there are no exceptions. All females have sex if they want.
Even obese, disfigurated, down syndrome females have boyfriends and sex. The cucks, soyboys and other sick men, have fallen that low. So low that even those 0/10 females have access to sex.
So just erase "femcels" from your dictionary, it doesn't exist. Only men are Incels.
