Andrea Millwood Hargrave's 2000 study of the attitudes of the British public found that fuck was considered the third most severe profanity and its derivative motherfucker second. According to linguist Pamela Hobbs, "notwithstanding its increasing public use, enduring cultural models that inform our beliefs about the nature of sexuality and sexual acts preserve its status as a vile utterance that continues to inspire moral outrage." Hobbs considers users rather than usage of the word and sub-divides users into 'non-users', for whom the word "evokes the core sexual meanings and associated sexual imagery that motivate the taboo", and 'users' for whom "metaphorical uses of the word fuck no more evoke images of sexual intercourse than a ten-year-old’s ‘My mom’ll kill me if she finds out’ evokes images of murder," so that the "criteria of taboo are missing."
