Coupler

A coupler is a person, usually male, that is penetrated sexually from both ends. Thus acting as a coupler for the other two partners. This is also referred to as not being "just gay" but "double gay". Which has been scientifically proven to be twice the amount of gayness.

He's such a slut. He's a coupler for both Terry and Julian when they do the sex.

Terry Folds

Terry Folds, while similar to Terry Flaps, are classified as any loose bodily skin flaps that can be used for the purpose of self gratification, or more commonly, fornication using non traditional penetration and sexual friction.

We got so crazy last night that I stuck my dick in Beth's armpits and nailed those Terry Folds.
