Vaguely you can refer the meaning Item Songs to some catchy upbeat dance number in the movie without much relevance to the story of the film. A item song normally happens in a night club or disco. In earlier years of movies, Helen used to dance to some songs which can roughly be referred as item number. But those were not very sexy or suggestive as they are today. To give competition to Helen is Bindu and to some extend Aruna Irani.
