Someone who has no clue about Facebook.

Possibly afraid to even use Facebook.
Could also be someone new to Facebook, most likely a 50-something that has no clue how to post or tag content.

The Facebook Tard usually has 20-something off-spring that school them on the nuances of social networking. These off-spring often use encouraging statements like, "Facebook is good for old people like you. MySpace is for young people."
My mom is so Facebook Tardilicious that I had to post her profile picture for her.

My Facebook Tardilicious friend published the same link five times!
