There are several urban-legend fake etymologies postulating an acronymic origin for the word. In the most popular version, it is said that the word "fuck" came from Irish law. If a couple committing adultery were "Found Under Carnal Knowledge" they would be penalized, with "FUCK" written on the stocks above them to denote the crime. Alternative explanations for "fuck" as an acronym for adultery pin it as "Fornication Under Cardinal/Carnal Knowledge". Another story is that it was written in the log book as "FUCK" when people in the military or navy who had homosexual intercourse were being punished. Variants of this include "For Unlawful Carnal Knowledge",
