The day after a sleepover, you take one. Involves a shower, (you didnt take one at your friends house) tooth brushing, (you forgot it) hair making, (because you didnt do it), and any other normally morning things done mid day after a sleepover. ALSO could be after a hangover.
"Hey bro, you wanna hang out later?"
Ya dude, but let me just take my sleepover revival, i look like shit!"
