facebook twin
A Facebook user who either looks like your ugly mug or has the same name as you. Probably a total dud who got stuck with your face.
My cousin found my Facebook twin and sent me a message: 'Is this you? You look like you got hit by a truck.'
My teacher called me out for cheating because my Facebook twin had the same name and sat in the back of the class.
I told my mom I found my Facebook twin and she said, 'That’s your uncle. He’s been using your face for 20 years.'
