When having a sleepover you stay up all night, and the next day you are extremely exhusted and lathergic.
Winston: You look like a zombie, what time did you fall asleep?
Oscar: James was over last night and we didnt get to bed to 5.
Winston: You might want to get some sleep.
Oscar: Yea I know, it's from the slumber party hangover.
