Jawaani used to be Kamsin, but it seems with the changing times it has become 'Halkat' and indeed the sense of halkat has been brought out in a rather brutally sexual manner by the item song that has been picturised on Kareena Kapoor in the Madhur Bhandarkar's new film Heroine.
Traditionally Jawani with reference to Hindi cinema was considered to be rather naive, full of innocence and joy de viv, but these days it seems with the exposure to the content through all kind of information network and devices, before one really becomes jawan, he or she is aware about the paraphernalia associated with Jawani and therefore it is not out of place to call it as 'Halkat Jawani'. Halkat after all is an attitude, attitude of not bothering about what others say about it, but just push along and enjoy life to the most.
