Foid is a shortening of “female humanoid,” a term incels use to refer to women, because the word woman allows too much of a sense of humanity. Rapecel (used sickeningly commonly online, to the extent that it has spawned its own forums and discussion groups) denotes an incel who simply resorts to rape to “resolve” his sexual frustration. The creation of a single, offhand word to describe this somehow makes it seem like a normal, even mundane notion.
