Like a bachelor party for fictional, not-yet-dating couples. The narrative often drives the StarCrossedLovers into a relationship or fling juuuuuust before they finally hook up for good. Perhaps so they can sow wild oats or learn important lessons about their partner, or on the opposite end of the scale, who to trust with an unattended drinks. Sometimes these last minute hookups are used to get the other party to realize the error of their delays. Often, this is the very first relationship in a long time for the flinging party, since they've been so entrapped by the ongoing will-they-or-won't-they nonsense.
