Noun-A Relafriendship is a relationship between two people that has "extra" benefits but doesn't constitute a true commitment to each other. Both parties can act as though a real relationship is underway and even have feelings towards each other, but it can also end at any time without ties. One or both parties are often times married to someone other than their "relafriendship" partner. Most relafriendships are on the "low" except to very close friends.
Though everyone thought they were together, it was nothing more serious than a relafriendship.
