bobble head

A person, usually a student or a lower position employee, who always blatantly shows agreement with their teacher or superior by constantly nodding their head when in the presence of their colleagues for the purpose of getting recognition or acknowledgement just for staying awake (no matter if actual agreement can be or is felt). This perpetual motion, which commonly plagues gunners, is often combined with furtive glances at fellow colleagues to help build own self-esteem in the sense that others don't seem as interested in the lackluster drivel coming out of the boss's mouth. This is one of the most implicit ways of kissing ass, though easily observed in places like medical schools and probably board meetings. In other words, where fear-driven type-A individuals are spawned.
