well i don't think the movie was named so after coming up with the song. as far as i know (from film news, on net, newspapers..) the film was first named tara rum pum pum, and one `pum' was removed later. that looked more like being in line with the recent trend of naming the movie with an old hit song title.. (and then making a song with same line but make it sound somewhat different from the original song).. like kabhi khushie kabhi gham, bas itna saa khwaab hai, kabhi alwida naa kehnaa..
