How to create that "Woosh" Sound?

[outnertia]

Ok, its bugging the hell out of me...

Theres a really nice and effective sound that a lot of quality films have [mainly action and horror movies]. Im talking about the one they use during a transition wich has the appearance that the camera is panning quickly to the next shot acompanied by a "Woosh" sound [not the quick one wich sounds like someone threw a quick jab but a deeper and slightly longer one].

Does anyone know how i can create this sound at home? or maybe a place i can download a similiar sound?

I have FL Studio for sound editing and a usb microphone. Having FL Studio aslo means i have a bunch of other musical instruments that can be reversed, slowed down etc.

If anyone is still confused, i will try to explain better somehow.
