The song's lyrics are considered vulgar by many because they contain sexually suggestive innuendos and references to physical intimacy. Some critics argue that the song promotes a negative and objectified portrayal of women, as the lyrics focus primarily on their physical appearance and sexual appeal. The lyrics also include references to "breaking the bed" and "making love in the moonlight", which some find inappropriate and offensive.
However, supporters of the song argue that it is simply a fun and entertaining dance number that should not be taken too seriously. They point out that many Bollywood songs contain similar suggestive lyrics and that "Is Sila Ki Jawani" is no more explicit than other popular songs in the genre.
Ultimately, whether or not a song is considered vulgar is a subjective matter that depends on individual perceptions and sensitivities. What some people find offensive, others may find harmless or even enjoyable. It is important to respect different opinions and perspectives when discussing music or any form of art.
