The term 'foid' is a controversial slang word that originated within 'incel' (involuntary celibate) online communities, serving as a shortened version of the portmanteau 'femoid' (female + humanoid). The term is intentionally dehumanizing, used to strip women of their individuality by framing them as robotic or biological entities rather than human beings. It first appeared in the mid-2010s on platforms like 4chan and various fringe message boards. In broader meme culture, the word is often discussed in a socio-critical context to highlight the language used in toxic subcultures. Understanding the term is essential for navigating modern digital linguistics and identifying the jargon used in specific online echo chambers.
