In an odd numbered circle jerk, it is the man responsible for two other participants and any choreography or direction changes which are dictated by the experience level of the group.
A person who is in the center of a Circle Jerk bent over pivoting around to service the circle jerkers, however at the time of ejaculation, the cirlce jerkers give the pivot man an angry pirate.
"Dude, right when I came, i shot in his eye and kicked him in the shin... oh yeah, i made him an angry pivot man."
