opportunity cock

An opportunity cock is the man who is not chosen by a girl when she has to make a choice between 2 guys. Deriving from the term opportunity cost, meaning the item not bought when choosing between 2, the opportunity cock is basically the man the girl leaves behind at the bar when she sees a much more attractive rich man.

John: “Can’t believe Ann chose Andrew over me. What’s wrong with me?”

Jim: “Damn, you’re the opportunity cock in this situation. Rip mate”
