Fart is an English word which literally refers to flatulence. The word is generally considered mildly offensive and unsuitable in a formal environment by modern English speakers, though conservative locales may consider it vulgar. “Fart” can be used as a noun or a verb.

While it primarily denotes flatulence, it has other meanings: the phrase “to fart around” refers to goofing off or wasting time; an “old fart” is a somewhat derogatory term for a old-fashioned or elderly person.
