Hinge 

In a closed polyamorous relationship where two people are NOT involved with eachother but are both involved with a third person, this third person is known as the hinge.

This comes from the visual of a hinge, with two things connected to it but not to eachother and still functioning as a whole.

This could be considered the opposite of a unicorn.

In Alex, Jaden, and Morgan's throuple, Alex is the hinge.

Hinge Penis 

A penis which swings on a hinge allowing for the optimum angle if the male is off center to the female. Great for situations when one does not simply wish to move left or right, they may just swing their penis.

"Man, I wish I didn't have to move right now." "Its ok honey, I can just swing my hinge penis."
