When you feel like your cell phone is vibrating or hear someone calling your name, but in actuality, no one is trying to make contact with you. You pull out your phone in vain, seeing that you've missed absolutely nothing. The illusion of being popular enough to warrant random "hello"s via wireless device or face to face.
