Facebook whirlpool
When a Facebook addict gets stuck for hours and hours reading friend's status updates, posting pics, searching for long lost friends, sending gifts, etc., until he or she loses all perception that the outside world exists.
Kevin told me that he spent from 9:30 PM to 3:00 AM last night stuck in an absolutely deadly Facebook Whirlpool. He forgot to eat dinner, walk the dog, and completely blew off his date.
