Definition
A "yawner" is someone who yawns, often indicating boredom, tiredness, or sometimes even stress. It can also be a slightly derogatory term for something boring or uninteresting. It's generally an involuntary action, triggered by a lack of oxygen or a physiological need. Yawning can also be contagious, spreading from one person to another. It's like a silent signal of fatigue or disinterest. Unlike a sleeper, a yawner is awake, at least for the moment.
