Similar to a Scandinavian Sandstorm where you take a high powered fan and face it to a girl. Jizz at the fan and it will blow back and hit her in the face. However, it is done using the Dyson Air Multiplier and consequently shoots in more of a wad shape.
She requested the Scandinavian sandstorm, but unfortunately the Dyson was the only fan in the house. Five minutes later the Scandinavian Snot Rocket was dripping down her forehead.
