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.

To grab your schwanz and have some tool grab your forearm and move it up and down, like he's steering the dick boat into orgasm harbor
SnackCake gives the worst Dutch Rudders ever. It's like a mentally retarded Chinese monkey trying to play the banjo.

When you grab a seated friend's penis and set your elbow on his knee, the friend continues to bounce his foot to preform the act of masturbation.

When a man masturbates, and another person grabs his arm and makes him do the motion. It's sort of like a cross between masturbation and a handjob. He is still holding on, but the other person is still moving your arm.

The frothy mix of semen and lubricant created when one ejaculates and then uses said ejaculate as fresh lubricant for a second jack session.
After I splooged in that Dennys bathroom I got a creamy batch of rudder butter going on cause I had to go for round two.
