church nod

when you start to fall asleep while sitting upright and quickly snap or bob your head back up

derived from people bored at a speech, or spefically church sermon, who begin to "church nod" as they try not to fall asleep

see also "four-wheeling"

In lecture the other day I got picked on when the teacher saw me church nod.
