Facebook denier
A grown-up who says they’re not on Facebook, but they’re always on it. They’re like a person who says they don’t smoke, but they’re lighting up a cigarette every 5 minutes.
"I only check Facebook once a day!", then they check it 4 times before lunch.
"I don’t need Facebook!", then they get mad when they don’t get a comment.
"I only use Facebook for fun!", then they spend 2 hours looking at their old posts.
