Definition of fuck all

The origin of the term "fuck all" is not completely clear, as the exact time and place in which it first appeared in the English language is uncertain. However, it is commonly believed to be a form of rude slang, originating from the bawdy and vulgar language of the underground urban culture of the mid-20th century in the UK and the US. The phrase "fuck all" is an intensifier used to express a degree of negative intensity or worthlessness. Its literal meaning is "fucking nothing," implying a complete absence of something, but is used as a more emphatic version of "absolutely nothing" or "noone/nothing." Its origins are likely rooted in the use of the noun "fuck" as a verb, indicating an intense sexual act or strong displeasure, in colloquial British and American English since the late 19th century. The addition of "all" as a suffix has also been linked to the shorthand expression "FLU" (Fucked-up, Lost, and Unconscious) which was popularized in literary and musical subcultures in the 1960s and 1970s. This acronym, and by extension the phrase "fuck all," reflects the context of adversity and desperation which has become associated with this term since its inception. As a slang term, "fuck all" is recognized as a taboo phrase due to its provocative and obscene nature, particularly in more conservative cultures. Its usage is typically frowned upon in formal situations and is generally restricted to informal communication between close peers and friendly social groups.
