(Wow-O-Ver)- When you play World of Warcraft for a long period of time during the early AM hours then going to sleep and waking up in the PM hours with images of World of Warcraft and a headache.
Walnut: Dude I have to stop playing at 11

Brandon: Why?

Walnut: I got a Wowover when I woke up at 2PM, my head was pounding, and I think I also yelled "For the Horde!" to my mom when she was yelling at me to wake up...
