co-bitch 

In a double date, when a man requests his bitch to bring her friend as the second man's blind date.

Jack: "Hey, why don't you come out with Betty and me this Saturday? Jim: "Well I don't want to be a third wheel." Jack: "NO problem, I will have Betty bring her co-bitch, then there will be four of us".
