A more correct term for sleep over. The word 'sleepover' is misleading as it implies that sleeping will occur. However, this is simply not the case. The point of a sleepover is to stay up as late as possible in order to maximise party time. Thus, in all actuality the event termed 'sleep over' is more like an 'awake over'.
