The act of performing the dutch rudder in a circle with more than for people. Similar to a circle jerk, only one person grabs their dick and the arm of the next person and moves the other persons arm up and down. This happens in a consecutive line having all members of the
ship "rowing" at the same time. At least four people are needed to constitute a
dutch slave
ship.
Hey dude did you bring Dave? We need a forth to make this a real
dutch slave
ship, otherwise its just a bunch of dudes dutch ruddering... which would be
homo.
