After coming out of a relationship, very quickly finding a new love interest of greater value than the previous relationship. Like a traditional rebound, but with a better chance to score a new relationship with a better mate.
Guy 1: Dude, one happened to that one chick you were talking to?
Guy 2: I dumped her because she was a skank. But I found this awesome girl the next day!
Guy 1: Nice offensive rebound! You're really controlling the boards!
