noun.The momentary lapse of self-awareness one experiences after prolonged mobile device usage suddenly leads to a blunt snap back into reality. Symptoms include, but are not limited to deterioration of short-term memory, sense of direction, motor functions, speech, and courtesy. Mobile Dementia, or Mobile Mania as it is known in many public transit systems, can last as little as a few seconds or as much as a full minute while the inflicted try to figure out where the fuck they were going, how to fucking get there, and who the fuck they think they are.
That guy in the suit was frantically typing away on his blackberry until we reached the end of the line. When the train doors opened he was struck by Mobile Dementia and started looking around like he wasn’t sure he was suppose to be on a train in the first place. Instead of stepping aside to let the rest of us off, he spun around in circles and slowly made his way to the stairs. He made it all the way to the top when the mobile dementia wore off and he realized he had missed his stop and needed to go back.
