1. The sound when a bullet flies through the
air, or someone lands a punch in an old Bollywood movie (like the old
pow, bam in 1960s Batman)
2. Used similarly to the expression Mojo to refer to libido, self-confidence, style and sex-appeal. E.g. if Austin Powers had been
Indian, he might have
lost his Dishoom and not his Mojo!
The word Dishoom probably goes back to the 1975 Ramesh Sippy film Sholay with Amitabh Bacchhan which is considered to be a Curry Western and is the highest grossing film in Bollwood
