Facejacking
When a friend or enemy takes over your Facebook and posts stupid stuff to make you look like an idiot
My friend posted that I was a lousy dancer and put a video of me dancing badly. My face turned red.
My ex took over my Facebook and posted that I was a cheater. I got 100 messages from my friends.
My cousin took over my Facebook and posted that I was a total loser. I got 200 likes and it was embarrassing.
