The sound in question is a joke you can play at an airport, when a plane
arrives from a country where you'd expect people with unpronounceable names
like Saudi Arabia. The name you would give to get the sound you just heared is:
Makollig Jezvahted and Levdaroum DeBahzted. Which results in almost
everybody pronouncing it as "My colleague just farted, and left the room, the bastard."
