Post Traumatic Jacking 

After a serious drama in someones life, said person goes to relieve themselves of the problems that have occurred recently. Through a serious amount of rubbing yourself and waiting to ejaculate.

Friend: Yeah, he has had a lot of issues lately
Stranger: Yeah, his mom just died recently.
Friend: Wouldnt be surprised if he wasn't Post Traumatic Jacking right now.

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.
