Americans, bilingual in Russian and English, often laugh  among themselves at the title of this movie. There is, of course, no  joke intended. As are the English words "fortune" and "fortunate",  the Russian word "fart" is derived from the Latin "Fortuna", the  Roman goddess of luck. It simply means "luck". (For those who now  absolutely must know, the Russian word for the other is "pukanye".)
