An Australian phrase for the noise made by a loud blow-off valve on a turbo car, particularly a VL Turbo full of wankers who think they are cool, with their hats on sideways doing bog laps of the city with the stereo turned right up.
When the throttle is released the air rushes through the BOV causing a loud "Tutututututu" noise. Sounding like a pigeon on LSD.
