The Brief: A Black incel is known as a blincel.

DEEP DIVE
A blincel is a Black incel. This slang term is used to reference a Black male who is not able to attract a sexual partner.
The term is derived from incel, which stands for “involuntary-celibate.” This term refers to a subculture of men (typically white males) who spend most of their time online and have difficulty interacting and attracting partners.
Incels’ online activity consists of writing misogynistic, racist, self-pitying, and self-loathing messages in online forums and chats. Incels are characterized by their feelings of entitlement.
