Rock-Pissing Dump Truck
A “Rock-Pissing Trump Truck” is a very large dump truck FULL of rocks, and the rocks are pissing out all over your vehicle. These rocks are chipping the paint and hitting the windshield. And the truck has the nerve to post a sign saying “not responsible for any damage” and “stay back 200 feet”.
Rusty was so angry at the “Rock-Pissing Dump Truck” ahead of him. He pushed the gas pedal to the floor and went 85 mph to pass it!
