When someone logs onto your account and as a joke writes shit that you would never ordinarily say in your status bar, most of it being stuff to make the person look gay.
Matt: "Yo why did you write 'I love cocks' in your fb status last night?"
Jason: "Dude that wasn't me, someone totally status-jacked me!"
When someone you don't especially like leaves an unwanted comment on your facebook status, so people you want actually commenting and liking it tend to avoid it for fear of getting a response from the unwanted commenter.
A facebook, twitter, or other social media status update that serves only for the psychosocial gratification of the poster, not unlike sexual masterbation.
-Did you see Lisa's most recent facebook status update about how happy she is with her life and how thankful she is for everyone?
-Yeah, I did, and I can't stop reading it. I have such a fetish for reading status masterbation.
