The incel (ˈɪnsɛl , a portmanteau of "involuntary celibate") subculture is an online subculture of people who define themselves as unable to get a romantic or sexual partner despite desiring one. Discussions in incel forums are often characterized by resentment, misogyny, misanthropy, self-pity and self-loathing, racism, a sense of entitlement to sex, and the endorsement of violence against women and sexually active people. The Southern Poverty Law Center (SPLC) described the subculture as "part of the online male supremacist ecosystem" that is included in their list of hate groups. Incels are mostly male and heterosexual, and are often white. Estimates of the overall size of the subculture vary greatly, ranging from thousands to hundreds of thousands of individuals.
Since 2014, multiple mass killings have been perpetrated by self-identified incels, as well as other instances of violence or attempted violence. Incel communities have been increasingly criticized by scholars, government officials, and others for their misogyny, the endorsement and encouragement of violence, and extremism.
The first website to use the term "incel" was founded sometime between 1993 and 1997. The website was created by a university student living in Toronto and known only by her first name, Alana, to discuss her sexual inactivity with others. Titled "Alana's Involuntary Celibacy Project", the website was used by people of all genders to share their thoughts and experiences. During 1997, she started a mailing list on the topic that used the abbreviation INVCEL, later shortened to "incel", for "anybody of any gender who was lonely, had never had sex or who hadn't had a relationship in a long time". During her college years and after, Alana realized she was bisexual and became more comfortable with her identity. She stopped participating in her online project around 2000 and gave the site to a stranger. In 2018, Alana said of her project: "It definitely wasn't a bunch of guys blaming women for their problems.
