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.

postjacking 

"Postjacking" is when a couple or a few people take over a comment string, usually on Facebook, and subsequently take things in a whole different direction. This is not inherently a negative thing, as it can often be amusing to witness.

Sorry for postjacking your string, Dude! We'll let things get back on topic now.

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.

Petjacking 

Petjacking

When a person's social network site status or conversation is followed up with a comment made by a friend about the friends pet or pets, when it has nothing to do with the conversation. The pet owner wants to steal the conversation to talk about their favorite topic, their pets.

Typical petjacking:

Person "I went to an awesome concert last night"

Petjacker "I feel guilty going anywhere after work because my dog misses me so much when I'm gone"

Poshpacking is like backpacking but staying in nice hotels rather than hostels.

We are poshpacking around Asia.
