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
A sex act in which a man ejaculates into a woman's nasal passage, filling it as much as possible. She then forces air through her nostrils, pushing the sperm into her mouth, which she subsequently swallows.
"Dishoom" is the old sound effect used when someone would punch someone else(<i>a la</i> "pow!" or "bam!" or "sock!") in old Bollywood movies. Splendidly appropriated by Badmash.org's Flash parody of the 2004 Presidential debate.
