The act of nodding off, then upon realizing that your head has fallen forward, pulling it back up in an attempt to stay awake. Happens most frequently while in front of a computer working on a boring report or in long meetings/lectures/classes.
Dude. Did you see Jim head surfing through today's Econ 101 lecture? He was fighting hard to stay awake!
