A nautical technique used to direct sailboat's when the rudder is broken. One party on the boat inserts his penis into another's anus, thereby placing fecal matter on the penis to use for grip. The penis is then dipped in the water to provide direction to the craft.
We were in a tight spot when the boat lost it's steering, but I used a muddy rudder to get us back on course.
