A combination of the words "Facebook" and "fake." Describes a false relationship status showing your relationship status on Facebook as married, when you are not actually married to the person. It can discourage people from hitting on you but more then likely you just married your best friend to avoid posting your actual relationship status on Facebook.
"I love my Fakebook marriage: I didn't want that guy to bug me about our relationship status on Facebook. Thank god I told him I'm married to my best friend and it would hurt her feelings if we broke it off."
