A person (guy or girl) who immediately starts dating someone who just out of a serious relationship. This person is usually there on the 'rebound' to fill the void left by the previous significant other.
Liz just broke up with her boyfriend of three years and now Jeff's dating her. He's a pathetic rebound fuck.
