Fart is an English word which refers to flatulence. The word "fart" is generally considered unsuitable in a formal environment by modern English speakers, and it may be considered vulgar or offensive in some environments. Fart can be used as a noun or a verb.By the early twentieth century, the word fart had come to be considered rather vulgar in most English-speaking cultures. For a long time, the word was forbidden from the public airwaves in the United States. [citation needed] While not one of George Carlin's original seven dirty words, he noted in a later routine that the word fart (along with turd and twat), ought to be added to "the list" of words that were not acceptable (for broadcast) in any context (as opposed to words such as ass, cock or pussy which have non-offensive meanings).
