A friend group of three where two of the persons are in a relationship and the other is a friend of both. Many times the third person is called a "third wheel". Replace "third wheel" with "frouple".

Frouple = friend/couple.
On the show 'How I met your Mother' Marshall & Lily are the couple and Ted is their best friend. They are the perfect example of a "frouple"
