Drawing on your friend with a sharpie before they wake up (usually without their consent).
This usually happens at sleepovers.
Basically, the first person (or people) to wake up get to draw on everyone else with Sharpies. Of course there is always the risk of getting your friends really mad.
"Aw dude! Those two got up first and they sharpie raided everyone! I now have a drawing of a monster coming out of my ass."
"You think that's bad? Look at what they did to my face!!!"
