Within the context of dating, to rebound refers to the undefined period of time following a particularly painful break-up, when the reboundee is psychologically incapable of making healthy judgements and decisions regarding suitable partners often involving breaking The Rules. ie. "Nick is on the rebound."; "Jane is Nick's rebound". If it is used in the latter sense, then a rebound is described as the partner that someone has following a breakup.
