Facebook Franker
A person who can't send a message without stealing someone else's Facebook login because they're too cheap to get their own account.
I had to use my friend's Facebook to message him because I didn't have money for a data plan. He was confused.
My sister used my dad's Facebook to tell me she was coming over. He thought it was a prank.
I had to borrow my neighbor's Facebook to tell him I was coming to his house. He just said, 'You're here now.'
