Rebound (dating)
A rebound is an undefined period following the break up of a romantic relationship. The term's use dates to at least the 1830s, when Mary Russell Mitford wrote of "nothing so easy as catching a heart on the rebound". The term may also refer to a romantic relationship that a person has during the rebound period, or to the partner in such a relationship.
