private party 

seriously I can't believe i'm the first person to put this in...
then again its not really an urban word...

n. party of close friends with few if any outsiders, typically in someone's house/basement/garage/apartment above the garage. typically involves large amounts of alcohol and shenanigans

that time we hung out in Rachel's aunts garage and got so blasted on jello shots, had Sir Nicklington run the gauntlet and boosh chugger chugged a bush lite and puked gloriously on video.....THAT was a private party.
