A relationship you build which is only useful for a short period of time. Perhaps with a client, a fling, the guy next to you on an airplane or bus, a fellow sports fan at a bar or any other form of good human contact which will end after a short period of time.
We became best friends in about 5 minutes, but it was just a throw awaytionship and i'll never see them again
