Postjacking 

When someone comments on a Facebook post such as a wallpost, status update, or anything else in an attempt to bring in another conversation and divert attention away from the post and toward themselves.

Jason posted on Marie's Wall:
"Hey...how have you been?"
Jack commented on Jason's wall post:
"JASON! Why didn't you text me back?"

And Jason and Jack have a conversation on the wall post that was meant to be for Marie, and thus Jack postjacked the conversation. Postjacking can also occur in status updates, but it most common on wall posts.

podjacking 

To hijack someone else's iPod (esp. w/car interface, while owner is driving) and change their playlist of choice to one you prefer--without their consent, knowing they are unable to interfere. Can imply a criticism of the owner's taste in music.

Dude--don't be podjacking me! I just put that playlist together! My car, my tunes...

Ugh--this music sucks. I'm podjacking you.

PodJacking 

"PodJacking" (sometimes "iPod Jacking") occurs when an individual equipped with an iPod and radio transmitter, accidentally or intentionally overrides another individual's radio. The result of setting the transmitter to a frequency in use locally. Happens most often in cars while on the road.

"I was driving around and grooving out, but this jerk pulled up next to me and PodJacked my radio! All I could hear was the Backstreet Boys, I hate PodJacking!"

postjack 

Antonym of prejack, postjack is the capacity, (exclusive to men), to think clearly, make responsible purchase decisions, refuse to comply with the suggestions of hot women, do math, and pass strip clubs without going inside. Typically a momentary, fleeting state that goes away a few minutes "postjack".

Postjack it’s pretty clear to me how much I hate that fucking couch she made me buy, and how – frankly – I’d really like to strangle her goddamn cat… but the feeling usually subsides after a couple minutes, confusion sets in, and I have to go look for my calculator and a dictionary… wait, what was I talking about? I need to go look at redtube.
