This only happens once a year, usually on the fourth of July. A man and a woman join in sexual relations, and the man dips his man meat in caramel and he puts it in the freezer and waits for the caramel to harden. Then the woman lays on the floor and the man gets running start, then at full speed he rams the woman in her shitnozzle. He will then proceed to push the woman around on her face, thus the name "Rusty-crusty bulldozer".
My girlfriend is all pissy now cuz she got rugburn when i gave her the Rusty-crusty bulldozer.
