A femcel is woman claiming to be experiencing inceldom (involuntary celibacy) or volceldom (voluntary celibacy). The antonym of femcel is mancel. The culture, norms and hunches that permeate the femcel communities are referred to as femceldom. The most notable femcel in popular culture is probably Rogue, a fictional character from the comic series X-men, whose inceldom is caused by the fact that her physical touch produces an involuntary deadly high-voltage jolt, thus preventing affectionate relationships with others. The femcel is a "2" on the decile scale, just below the femcelish woman. Nonetheless, she isn't at the bottom of the totem pole as femcels tend to mog (i.e. manage to one-up) the truefemcel woman in looks, social status and overall charm.
It is generally accepted that involuntarily celibate women don't exist with the exception of women that have medical issues like vaginismus, terminal illness, horrendous lesions all over her body, mental disabilities that would make an adult relationship impossible (e.g., Down syndrome), or if she lives is in a sexless relationship caused by the man, or is in a country with arranged marriages. However, with incelbian women it's a different story, since some lesbocels tend to live in conservative deep red states who can't find any other lesbians anywhere within their vicinity; and if they do, these lesbians are usually in the closet, so out of reach. Of course women can be sexless, but this is largely self-inflicted because men have a higher sex drive meaning there will always be men around willing to sexually satisfy any woman
