Facebook denier
A person who won’t admit they’re a Facebook addict, but they’re always checking it. They’re like a kid who says they’re not hungry, but they’re eating a whole cake.
"I don’t check Facebook that much!", then they open it 4 times in 5 minutes.
"I only use Facebook for work!", then they spend 2 hours looking at pictures of their ex.
"I don’t need Facebook!", then they log on 3 times before bed.
