Incel
"Incel" refers to someone who is involuntarily incelibate, stereotypically a male. Incel attitudes are commonly exhibited on Reddit/4Chan/8Chan forums and in comments section of media containing women. Colloquially, it entails entitlement to female body parts and attention, male supremacy, male victim mentality, entitlement to absolute respect from the society's vulnerable populations (sex workers, women, trans woman), harassment of women on the internet, and even acts of physical violence. It significantly overlaps with misogyny and is seen most in highly individualistic cultures. The internet is not a friendly place for women because of them.
Femboy
Stereotypically, a femboy is a genetic male with a naturally androgynous appearance and feminine mannerisms. Femboys may identify as male or female, tend to self-identify as bisexual (in my experience), and may even undergo female hormone treatment to further feminize. I am a 25-year-old femboy, and I've had multiple feminizing surgeries and 5 years of hormone treatment. While many think I am a trans female, because of how feminine I look/sound, I just see myself as a continuation of the submissive boy I was in my teen years.
