Incel (Involuntary Celibacy)
Incels are members of an online subculture who define themselves as being unable to find a romantic or sexual partner despite desiring one, a state they describe as inceldom. Self-identified incels are almost exclusively male and mostly heterosexual. Discussions in incel forums are often characterized by resentment, misanthropy, misogyny, racism, entitlement to sex, and the endorsement of violence against sexually active women and more sexually successful men.

I dont know if it is actually a negative group as the description suggests or the wiki editor had something personal against them.
