the expression is taken from a supposed joke that an indian man tells his friend on the plane, on their way from the states to india:

So one day Santa Singh and Banta Singh are doing nothing, passing the time, staring at the sky, and all of a sudden an airforce plane flies by, men
parachute out of it, get into military jeeps waiting for them in the fields, and go home. ‘Arre, sala, this is the life,’ says Santa to Banta, ‘what a way to make your money.’ So off they go to the recruitment agency and a few months later, there they are in the plane. ‘Wahe Guruji Ka Khalsa,Wahe Guruji Ki Fateh,’ says Santa and jumps. ‘Wahe Guruji Ka Khalsa, Wahe Guruji
Ki Fateh,’ says Banta and jumps.
“‘Arre, Banta,’ says Santa, a second later, ‘this sala parachute is not opening.’
“‘Ai Santa,” says Banta, “neither does mine. Typical government intezaam, just you wait and see, when we get to the bottom, the bhenchoot jeep won’t be there.’”
