Passenger Seat Hijack 

The Passenger Seat Hijack is when a dude masterbates in the passenger seat of a form of transportation (car, van, airplane, etc.) while the rest of that vehicle is occupied by others. The "hijacker" then yells "jack, jacking, or jacked" as to let the crew members, and other passengers that they are experiencing a passenger seat hijack.

Bro 1: Dude how wasted did we get last night? Did Ryan really pull Passenger Seat Hijack on Christy's car?
Bro 2: Yea bro....Ryan was so hammered with his pants around his ankles and yellin "JACK! JACK! JACK!" while strokin his sausage in the passenger seat.
Bro 1: That dude's got issues. I'm never drinking with him again.
Bro 2: Tru.

The use of the 'comment' feature on someone's status update on facebook to conduct a personal conversation, unrelated to the status.

Pam: "Oh look! I have like 20 new notifications!"

Shotgun Hi-jack 

When someone has previously called shotgun, and then gets out of the car at all, without calling seat-back. The person who wishes to obtain the position of shotgun shouts "shotgun hi-jack" and takes the shotgun position.

Joe's homey get's out of the car... like a fool he doesn't call seat back... Joe being the genius he is calls shotgun hi-jack and takes the shotgun position. Joe's homey returns to the car... and realizes he is a fool and sits in a non-shotgun position.
