Trouple

It is a combination of "couple" and "triple" where the three individuals are in an equally inclusive relationship.

Tim, Pat and Lawrence all live together and share a california king while they enjoy being a "trouple."

thruple 

Three-way relationship. Properly known by polyamorists as a triad. Amusingly known by many gay men as a 'thruple.'

In a gay thruple, there is twice the sex, but six times the emotional baggage, as the joke goes.

Trouple

A couple who has a friend that is always with them becomes a trouple. The third person has to be friends enough or have been hanging out with the couple long enough to not feel like a third wheel, thus becoming a trouple.

It was decided that Gary was part of a trouple when he went with Frank and Tracy to Las Vegas.
