Unfortunately, High Valyrian, as constructed by George R.R. Martin and further developed by linguist David J. Peterson, does not have direct translations for modern English idioms, especially those of a vulgar nature. High Valyrian is a fictional language with limited vocabulary focused on the context of the "Game of Thrones" universe. Therefore, a culturally accurate equivalent does not exist within the language's current lexicon.
