Facebook camper
A Facebook camper is a person who sits on Facebook like a weirdo waiting for someone to log on so they can start a long chat about how their day was the worst and how their neighbor is a pain.
Message: 'Hey, you online? My day was the worst. My neighbor is a pain.'
Comment: 'Your post about your day was fake. My neighbor is a pain.'
Post: 'Had the worst day. My neighbor is a pain. You? How was yours?'
