Incestophilia

(Noun)
A hybrid term combining the Latin Incestum (unholy/impure) and the Greek suffix - philia (attraction/love). it describes a paraphilia or sexual attraction toward immediate family members. Unlike the slang terms often used on platforms like Reddit (e.g., in subreddits like r/sibkisser), this term is intended to provide a formal, clinical-sounding label for the romanticization or active pursuit of incestuous relationships. A person who practices incestophilia is also known as an incestophilus.

"The growth of certain online communities has led to a disturbing normalization of incestophilia, often disguisd as irony or meme culture"
