When a friend forgets to logout of Facebook, Face-jacking is the art of making them appear to have written hilarious status updates about their own sister, become "fans" of lame things, and "like" anything and everything.

Not to be confused with a botched female circumcision, or jack nasty face
1. Cam: Why does Tim like my status?
Matil: Tim seems to like my status too?
Ben: Why would he like my status, when its just me talking about how good looking i am?

Matil: Looks like classic Face-Jacking

2. Why the hell am I a fan of both 'I hate crocks' and 'I hate the people who hate crocks' ?? Damn Face-Jacking...
