Facebacking
When you log into your wife’s, husband’s, boyfriend’s, girlfriend’s, or buddy’s Facebook just to post something stupid because you’re bored or you want to mess with them.
I logged into my ex’s Facebook just to post a photo of my cat wearing a hat.
My mom Facebacked my dad’s profile to tell him she saw his ugly cousin at the grocery store.
I posted on my friend’s wall just because I had nothing better to do and I hate him.
