when boyfriend and girlfriend break up, but still like each other. the members of the duo tend to maintain good friendships with one another, with the possibility of getting back together. roughly, a couple on a break.
Sally:: Yea yea, they broke up last week. Now they're a duo.
James:: Then why did they break up?
