When a friend of your has been with a girl who's a total bitch and she's about to move out, you have to throw a party. Have tons of people over and serve some drinks. If you want to really do it justice, have the party while the bitch is moving her stuff out.
John: Did you hear Adam's girlfriend cheated on him with that homeless guy that's always hanging around the drug store and that now she's moving out?
Tom: Yeah, she's moving out Thursday night and we're going to have ourselves a grand bitch leavin' party.
