This typically occurs when you leave yourself signed in to facebook/myspace on someone's computer and they change your status to something juvenille or ridiculously embarrassing. This can also happen from you leaving your iPhone or Blackberry some where with your facebook app accessible and your password saved. You can usually identify the culprit because they are the first to leave a comment or "like" your ridiculous status.
guy1: Hey man did you see Johnny's status? What's up with that?
guy2: Yeah man, but James commented on it 3 times in a row two seconds after it was posted so I figured he got status jacked
. You know he always leaves his iPhone everywhere. Homeboy needs to put a password on that thing.
Finding someone's Facebook/Myspace is still logged in and posting a new status update as them, usually to embarrass them.
