Iranian Bike Ride
An Iranian sexual act, in which one person rides an exercise bike and pedals without going anywhere. While the cyclist is pedaling away, another person proceeds to fling diarrhea at the cyclist's face with a spatula. The cyclist can pedal all they want, but they're not going anywhere on a freestanding bicycle.
Maz Jobrani may be a mildly amusing comedian, but the word on the street is that he gives one hell of an Iranian Bike Ride.
