Similar to motor-boating, mud ruddering involves grasping each side of the buttocks, gently spreading the cheeks and placing one's face on the poop shoot; then shaking the head back and forth as if saying "no" while proceeding to make a motorboat sound. Essentially, the buttock cleavage equivalent to motorboating. Unlike motorboating, mud ruddering makes no sex distinction, as you can mud rudder anyone who has buttocks.
