Testosterone Truck

A “Testosterone Truck” (almost always driven by a man) is any large truck that is driving aggressively and always rides your car’s butt when you’re driving. Even if you’re driving faster than the speed limit, the “Testosterone Truck” must always ride your bumper or pass aggressively.

“Julie was getting fed up with the many ‘Testosterone Trucks’ on the road that ALWAYS seem ride her bumper as if to intimidate, as they bear down on her car with their huge front end and bright lights”.
