The nightlife version of that ... people that call you Sunday to say "So hey, what happened at your party last night? Successful? How were the girls? Any good stories? Sorry I couldnt make it, my <insert lame excuse here>." The appropriate response - "It was amazing. Im not telling you any details. And because you didnt show, next time you're not invited." The silence on the otherside of the phone that follows is priceless.
