The money (respect, homage, etc) you owe your friend when he calls you to come to a party solely to hook up with the hot single chick who is drinking a little bit early and ready to hook up... and you seal the deal.
I owe R**n pimpimony after hooking up with the hottie last night... I wouldn't have come if he didn't call me and tell me about her.
